Definitions

  • the invention relates to a device for doubling cotton webs, as described in the preamble of claim 1.
  • Doubling i.e. Placing cotton webs on top of each other to form a new single cotton web serves to even out these cotton webs with regard to the length and the mixture of the staple fibers forming the cotton web.
  • the above-mentioned devices for doubling are mainly used on so-called sweeping routes known from the spinning machine market, in which a number of coils arranged next to one another each release their wadding web into a drafting system in which the wadding web is stretched and then immediately guided over a so-called sweeping sheet arrangement.
  • the stretched cotton webs are laid one on top of the other to form a new cotton web that combines all of the stretched cotton webs of the same machine.
  • the device can also be used on so-called cotton machines, which combine a number of stretched fiber slivers to form a cotton wool web lead and duplicate these individual cotton sheets to a new cotton sheet.
  • This wadding machine comprises sliver stretchers arranged next to one another, to which slivers discharged from cans are supplied.
  • the slivers stretched in the drafting system are combined to form a cotton web and, after the drafting system, are guided onto the collecting surface of all cotton webs by means of a baffle plate arrangement.
  • the dustpan arrangement is then connected to the drafting system, as seen in the conveying direction of the cotton web.
  • the individual cotton webs collected to form a new cotton web are fed to a winding apparatus for forming a cotton lap.
  • the above-mentioned bends have a structure similar to that of the cotton machines in that wadding rolls are used as a wadding web template instead of the cans supplying the slivers.
  • wadding rolls are used as a wadding web template instead of the cans supplying the slivers.
  • the individual drafting systems no longer stretch fiber strips, as is the case with the wadding machines, but instead wadding webs emitted by the wadding roll.
  • These individual stretched cotton webs are collected into a new cotton web in the same way as in the cotton machines and are also fed to a winding apparatus for forming a cotton roll.
  • the cotton balls of the sweeping sections then serve as a template for the combing machines.
  • the structure mentioned for the wadding machine, as well as for the sweeping section, has the disadvantage that, due to the drafting system, from the operating side
  • the machine is less deep due to the baffle plate arrangement provided below the drafting system. that is, the operator can also insert the fiber tapes or the cotton sheets from the operator side. Furthermore, there is the main advantage for the so-called sweeping section that the possibility of operating the drafting system from the front of the machine allows the wadding to be provided on the top of the machine, in contrast to the arrangements of the wadding on the back of the machine, as is the case in itself known prior art shows.
  • a sweeping section unit I (FIG. 1) comprises 2 rotatable support shafts 2 for receiving a cotton roll 3, a cotton wool conveying means 4, a cotton wool deflection 5, a dustpan arrangement 6 and a cotton wool collecting element 7.
  • the wadding roll Due to the rotation of the support shafts 2, the wadding roll is rotated in the direction of rotation R and thereby emits a wadding web 8 (also simply called wadding), which further into the wad conveyor 4 and then via the wadding web deflection 5 and via the dustpan arrangement 6 onto the cotton web collecting element located underneath 7 is performed.
  • a wadding web 8 also simply called wadding
  • the dustpan arrangement 6 reverses, in a manner known per se, the cotton web 8 supplied by the cotton conveying means 4 in a direction of conveyance rotated by 90 degrees to this conveying direction, as is shown with FIGS. 1, 2 and 3.
  • the cotton sheet collecting element 7 is a known polished sheet brass plate, but can also be a conveyor belt.
  • the cotton wool conveying means 4 is a drafting device for cotton webs (the roller pairs are indicated with dash-dotted lines in FIG. 1). Such drafting systems are known per se and are not inventive essential, which is why it is not discussed further. The same applies to the support shafts 2 and their drive.
  • the dustpan arrangement 6 is fastened to the machine frame 13 (FIG. 1) by means of a carrier 12 and is arranged below the cotton wool conveyor 4 in such a way that it is located inside the machine frame 13 and in such a way that the deflection 5 protrudes further into the space on the operating side than the dustpan assembly 6.
  • the cotton web deflection 5 is also fastened to the machine frame 13 by means of supports 14.
  • 8a to 8n show different embodiments of the cotton web deflection.
  • 8a to 8g and FIGS. 8k to 8m show stationary deflections 5.1 to 5.7 and 5.10 to 5.12 over which the cotton web 8 slides.
  • 8h and 8i show rotating deflections 5.8 and 5.9, respectively, which are mounted in roller bearings 15 and 16, respectively, the deflection 5.8 being driven by the cotton web 8 and the deflection 5.9 by means of a drive pinion 17.
  • the drive of the drive pinion is not shown and is done by means of a toothed belt driven in the machine frame 13.
  • the dash-dotted line in FIG. 8 indicates the cotton web 8, that is to say that the profile shown in the figures is the shape of the deflection.
  • the deflections 5.1, 5.6, 5.7, 5.8 and 5.9 have an elongated guiding surface, the guiding surface being understood to mean the surface on which the cotton web is guided.
  • the guiding surface being understood to mean the surface on which the cotton web is guided.
  • the guide surfaces of the deflections 5.6, 5, 10 and 5.11 which are inclined on one side with respect to the plane in which the cotton web is delivered, are used to steer the cotton web, either in the direction of the other side of the dustpan arrangement that is rounded with a radius r or opposite it 6.
  • the deflections 5.1 to 5.6 and 5.10 and 5.12 are U-shaped curved sheets, as shown in FIGS. 1, 7 and 4, while the deflections 5.7, 5.8 and 5.9 have a round rod shape.
  • the trough-shaped deflection 5.12 serves to simultaneously guide the cotton web 8 laterally during the deflection.
  • the cotton wool conveying means 4, the cotton web deflection 5, the dustpan arrangement 6 and the cotton web collecting element 7 are summarized as a 'device for doubling cotton webs'.
  • FIG. 6 The use of the aforementioned device in connection with the assembly of individual wadding machine units 50 (FIG. 7) to form a wadding machine 53 is shown in FIG. 6.
  • the cotton web 51 is composed of fiber tapes removed from cans 52 and in this composition on a feed table 57
  • W attebahn 51 corresponds to that of the lap sheet 8
  • the reciprocal distance, ie, the drawn cotton webs 51 are ultimately merged to the batting layer 10 and received by the lap roll apparatus.
  • FIG. 4 shows a variant which can be used in connection with the sweeping section and the wadding machine. It is a cotton web guide 18 provided at the beginning and over the entire width B (FIG. 2) of the dustpan arrangement 6 (FIG. 4). This cotton web guide 18 can be given the shaping shown in FIGS. 8b to 8f and 8k to 8n, so that guidance of the cotton web deflection 5 can be supported by this cotton web guide - provided the same shape as for the cotton web deflections 5.
