Definitions

  • the present invention relates to a sleeve for coiling with a roving, wherein the sleeve has an elongate sleeve body with two end faces, wherein the sleeve body has a designated for contact with a roving contact area, and wherein the contact area is at least predominantly formed by a paper layer.
  • Generic sleeves are known in the art and are always used when a roving on a textile machine, for. B. a flyer, must be wound up.
  • a corresponding sleeve is for example in the CH 681980 A5 described.
  • Roving (other name: sliver) is a fiber structure in which at least part of the fibers are wound around an inner core.
  • This type of roving is characterized by the fact that, despite a certain strength, which is sufficient to transport the roving to a subsequent textile machine, it is still delayable. The roving can thus with the help of a defaulting device, z.
  • a roving processing textile machine such as a ring spinning machine, are warped before it is finally spun into a conventional yarn.
  • the sleeve according to the invention has an elongated, preferably cylindrical sleeve body, which has an upper and a lower end face.
  • the sleeve body may be provided in the region of one or both end faces with inserts and / or attachments.
  • a lower attachment or attachment may be present, via which the sleeve can be held against rotation during the spraying with roving in or on a sleeve holder of a spinning or winding machine.
  • the attachment or attachment for example, depressions and / or bulges have to allow a positive or non-positive connection with a sleeve holder.
  • the attachment or attachment has an undercut, i. that the inner diameter is enlarged with increasing distance from the sleeve end opposite to the end of the sleeve, wherein a first portion is provided with about 30 mm axial length as a cylindrical opening.
  • a corresponding holding may be necessary either when winding the sleeve or its transport, wherein the attachment or attachment may have, for example, an opening for the engagement of a so-called Casablanca holder.
  • the undercut may be formed from the sleeve material itself without the use of an attachment or attachment.
  • the aforementioned inputs and essays can z. B. (at least partially) made of plastic or metal, preferably a biodegradable plastic is used.
  • the sleeve body has an outer, intended for contact with a roving, contact area which is at least largely, preferably completely, formed by a paper layer, the paper layer may also be multi-layer and thus may have multiple layers of paper.
  • a catch area for grasping a roving end with a catch structure This is a defined annular area of 2 to 50 mm axial length on the sleeve with a surface finish, which allows the entrainment of the empty tube on the sleeve.
  • the catching structure can be formed by a surface of sufficient roughness, for example by a brush plush, by sand or Korund vide, by embossing or by cutting the upper layer of paper. Alternatively, the Vorgarnfix ist done by aspiration of a designated perforated surface.
  • paper is to be understood as meaning a planar material which essentially consists of fibers of preferably vegetable origin and is formed by dewatering a fiber suspension on a wire, the resulting nonwoven being subsequently compacted and dried. Paper is usually made of pulp or wood pulp (eg groundwood).
  • paper in the present case also includes relatively high basis weight paper, which is also referred to as cardboard or cardboard, wherein the sleeve is held in the predetermined sleeve shape regardless of the exact type of paper with the aid of adhesive materials or other compounds.
  • relatively high basis weight paper which is also referred to as cardboard or cardboard
  • Another connection can be made for example by pressing individual paper layers.
  • Object of the present invention is to develop known sleeves to accomplish the aforementioned requirements easily and sustainably.
  • the paper layer is at least partially mechanically processed on its surface forming the contact area in order to produce the desired roughness and to prevent slippage of the roving from the sleeve.
  • the contact area is therefore not formed by a smooth paper layer. Rather, it is provided that the paper layer in the region of the contact area for the roving forming surface is at least partially mechanically changed either during manufacture of the sleeve body or following its production, so that the surface ultimately has a defined surface structure, which has a higher roughness than the non-mechanically processed paper.
  • the paper layer has on its surface forming the contact region at least in sections a roughened structure produced by mechanical action.
  • the structure may, for example, be effected by the action of a tool which brushes or scrapes the surface.
  • other mechanical treatments of the paper layer which cause damage or violation of the surface structure of the paper layer.
  • the mechanical treatment of the paper layer should be such that its surface roughness in the area of the correspondingly treated surface is higher than before the treatment.
  • the paper layer has incisions at least in sections on its surface forming the contact area.
  • the surface structure is created by means of cutting tools, whereby also here the cuts can be generated before, during or after the production of the sleeve body.
  • the incisions preferably take place in such a way that the surface has a serrated pattern defined by the incisions, so that the roving can easily get caught in this area with the paper layer.
  • this type of surface structure could be present only in a portion of the contact area forming surface to force the adhesion of a roving end at the beginning of the Bespulvorgangs.
  • the paper layer has, on its surface forming the contact area, at least sections of inserts which have a positive breast angle, i. that the protruding projections are inclined in the direction of rotation of the sleeve.
  • the breast angle is the angle between the perpendicular to the surface of the sleeve to the protruding supernatant.
  • the contact region could at least partially have a scale-shaped surface structure.
  • the paper layer is provided with an additive which increases the roughness of the surface in the interior and / or on its surface forming the contact area.
  • the additive may, for example, be glued to said surface. In any case, only a part of the contact area should be provided with the additive, the remaining area being formed by the paper layer. The additive is therefore preferably not applied over the entire surface.
  • the additive may be embedded in the paper layer, which may already be done during the production of the paper layer or during the production of the sleeve.
  • the additive gives the paper layer tiny bumps, which make the roughness of the contact area higher than without the additive.
  • the additive is a bulk material.
  • sand or a plastic granulate could be used as the bulk material.
  • the bulk material particles should have a maximum spatial extent of 0.05 to 1.0 mm and may have a spherical or oval shape or a form of rods, chip, fiber or thread piece or even with a jagged and / or edged shape.
  • the additive is covered by an outer and the contact area forming paper layer.
  • the sleeve has one or more inner paper layers, onto or into which one or more different bulk goods are applied or introduced. This paper layer (s) and the bulk material are finally surrounded by one or more further paper layers, so that the bulk material is not visible from the outside, but gives the sleeve a rough surface structure.
  • the paper layer has, on its surface forming the contact area, a surface structure produced during the manufacture of the sleeve body by overlapping individual paper layers.
  • the paper layer thus comprises a plurality of paper layers, which are preferably glued together and which are at least partially superimposed and fixed during manufacture of the sleeve body.
  • the sleeve body is produced by winding one or more paper layers on a later to be removed again supporting body.
  • the surface structure produced during the production of the sleeve body by overlapping individual paper layers has a diamond pattern.
  • the sleeve has a plurality of paper layers having different pitches with respect to a longitudinal axis of the sleeve.
  • other patterns such as wave patterns, patterns that consist of rectangular, in particular square or triangular basic patterns, conceivable.
  • the surface structure may be composed of different basic patterns.
  • the sleeve body is cylindrical at least in the contact area intended for contact with the roving, the outer diameter having a minimum and a maximum amount in said contact area, the minimum amount being at most 2.0 mm smaller than the maximum amount ,
  • the sleeve can of course also have a truncated cone shape.
  • the contact region intended for contact with the roving has surface sections with a surface structure deviating from one another.
  • a surface structure may be present which serves as a catch structure for a roving end, while the remaining contact area prevents slippage of the roving in the direction of the longitudinal axis of the sleeve.
  • a guide sleeve is inserted between the attachment and the undercut.
  • Such a guide sleeve has a smaller inner diameter than the end-mounted attachment, whereby a stable storage on conventional means of transport such as PegTrays can be achieved.
  • the sleeve and the guide sleeve are manufactured as in one-piece component.
  • an axial length of an inner diameter determined by the undercut is defined by a spacer sleeve.
  • the axial length is between 5 and 100 mm, wherein the inner diameter is 25 mm.
  • the spacer sleeve can additionally serve as a spacer between the guide sleeve and an insert provided with the undercut. As a result, a simple structural design of the sleeve is made possible.
  • a sleeve is provided by the present invention, which is simple and inexpensive to manufacture and thus can serve as a disposable solution.
  • the sleeve to be spooled with a roving at one location (eg, a spinning mill making conventional roving), and the spooled sleeve to be transported to another location (eg, a spinning mill or weaving mill) and there after Unwinding of the roving is disposed of. The transport of unwound pods back to the place of origin is thus obsolete.
  • Fig. 1 shows a longitudinal section of a sleeve 1 according to the invention, which is already gesppult with roving 2.
  • the sleeve 1 has a sleeve body 3 of cylindrical design in the present case with an upper and a lower end face 4.
  • the sleeve 1 With the help of a sleeve holder, not shown, a spinning or winding machine to be able to put in a rotary motion, the sleeve 1 has an attachment 12 in the region of the lower end face 4, which has an opening 15 and one or more protrusions 13 to a positive connection between the article To be able to train 12 and a sleeve holder of a winding or spinning machine.
  • an insert 11 is present, which likewise has an opening 15 and an undercut 18 in order to introduce a support structure into the sleeve 1 and to be able to lift and transport the sleeve 1 over it.
  • the insert 11 and also the attachment 12 may be made of a plastic.
  • the sleeve body 3 consists of a one or more paper layer having paper layer 9, so that the sleeve body 3 can be easily recycled.
  • the paper layer 9 is proposed according to the invention in a first variant is mechanically machined on its surface forming the contact region 5 at least in sections.
  • the paper layer 9, as in FIG. 2a shown has a mechanically generated structure 7, the z. B. may have a diamond pattern 10.
  • the structure 7 should be only a few hundredths to a few tenths of a millimeter deep, so that the outer diameter of the sleeve body 3 is substantially equal over the entire longitudinal extent in the contact region 5.
  • the paper layer 9 consists of a plurality of paper layers which have been wound in a different orientation to a sleeve body 3 (second variant).
  • Fig. 2b shows that the contact region 5 can also have several sections with different surface structure.
  • the sleeve body 3 has a structure 7 in the upper region, which serves as a catching structure 14 for Grasping a Vorgarnendes at the beginning of Bespulung serves.
