Definitions

  • This invention relates to a teaseling machine.
  • teaseling machines are currently available which comprise, in general, a rotating cylindrical drum having, connected, to its periphery, teaseling rollers set for rotation about their own axes, and hence performing a revolution movement relatively to the drum axis.
  • the teaseling rollers carry a teaseling liner which is provided with a thick series of metal hooks adapted to act on a fabric to be teaseled to raise pile thereon, thus imparting to the so treated fabric an attractive appearance which makes it suited to special applications.
  • the rollers In rotating about their own axes and rigidly with the drum, the rollers move past a cleaning station where one or more brushes remove any pile left on the metal hooks, thereby the machine proper operation can be ensured.
  • Another object of the invention is to improve the roller cleaning efficiency to provide an evener and better distributed reaseling effect.
  • a not unimportant object of the invention is to improve accident prevention conditions by eliminating the large rotary masses of conventional teaseling machines and potential failure of the latter due to centrigufal effect.
  • a not unimportant object of the invention is to facilitate control of the absolute speed of the teaseling rollers, to free the output rate from the mechanical ratio of fabric speed to teaseling roller speed, facilitate determination of the point of non- teaseling, i.e. that point where the peripheral speed of the teaseling rollers is nil relatively to the fabric entrainment speed, and afford low manufacturing cost, low space requirements, and a high versatility in use.
  • a teaseling machine comprising entraining members for a fahric to be teaseled cooperating with a plurality of taseling rollers set for rotation about their own axes, and characterised in that the rotation axes of said teaseling rollers are stationary relatively to the rotation axes of said entraining members and laid along a curvilinear profile having its convexity facing a passage zone of said fabric.
  • a teaseling machine according to the invention is generally indicated at 1. It essentially comprises a pair of entraining members located, the one at the machine inlet end, and the other at the outlet end thereof, being respectively designated with the reference numerals 2 and 3 and operative to feed a fabric 4 into the the teaseling machine while keeping it optionally under tension as it moves through the passage or teaseling zone 5.
  • Each entraining member preferably comprises an entraining roller 6, possibly arranged to cooperate with a small cylindrical tensioner 7 which increases the fabric angle of winding around the entraining roller and controls its tension.
  • the teaseling machine is provided with a plurality of teaseling rollers p, c set for rotation about their rotation axes and preferably parallel to one another and to the entrainzng rollers.
  • the rotation axes of the aforesaid teaseling rollers are stationary relatively to the rotation axes of the entraining members and arranged along a curvilinear profile whose convexity faces the fabric passage zone 5.
  • the teaseling rollers may be of conventional design, that is provided with a supporting body 9, with which a peripheral liner 10 is rigid, e.g. of the type having plural metal hooks effective to raise pile off the fabric, or alternatively, of the type shown in Figure 5, where between the conventional supporting body 9 and liner 10, there are interposed a plurality of ribs 11 preferably extending along generatrix lines of the supporting body so as to impart to the teaseling roller an active surface, whereon the hook liner is applied, having an irregular profile, and accordingly such as to apply vibrational effects to the fabric 4.
  • the vibratory motion so transferred further improves the machine tesseling capability to result in an advantageously increased hourly output without affecting the process quality.
  • the teaseling rollers may be distinguished as with-the-pile rollers and against-the-pile rollers, respectively as indicated at p and c.
  • the teaseling rollers will be preferably alternating with-the-pile and against-the-pile ones, so as to counteract the tractive forces applied to the fabric, and in that sense the cited rollers may be either alternated individually, as shown in Figure 2 where each with-the-pile roller is followed by one against-the-pile roller, or grouped in sets of with-the-pile rollers alternating with sets of against-the-pile rollers, as shown in Figure 1.
  • Each set of with-the-pile or against-the-pile rollers cooperate with a cleaning member, preferably a rotary brush 12 Which extends with its axis substantially parallel to the rotation axes of the teaseling rollers and is driven rotatively in a direction preferably agreeing with the orientation of the liner hooks.
  • a cleaning member preferably a rotary brush 12 which extends with its axis substantially parallel to the rotation axes of the teaseling rollers and is driven rotatively in a direction preferably agreeing with the orientation of the liner hooks.
  • both the with-the-pile and against-the-pile rollers are arranged in pairs and each set is associated with a cleaning member of their own which turns in agreement with the hook orientation while maintaining their axes of rotation stationary relatively to the rotation axes of the entraining rollers 6 and of the teaseling rollers p,e.
  • the rotary brushes are in this case carried oscillably on brackets 13, for example, journalled on a frame of the teaseling machine which carries the rotary parts in general, so that they can be switched from a with-the-pile roller to an against-the-pile roller to remain engaged with each of the cited rollers for preset time periods.
  • Figure 3 shows an exemplary construction of a drive assembly for the teaseling machine, as generally indicated at 20.
  • Both speed variators may be provided, on an output shaft 25 kinematically connected to the cited rollers, with clutch devices 26, e.g. electromagnetic clutches, to selectively control the operation and stopping of the with-the-pile and against-the-pile rollers.
  • clutch devices 26 e.g. electromagnetic clutches
  • the motor 21 is further connected, through a clutch device 27, to a speed variator 28 for the entraining rollers 6,7, which has an output shaft 29 preferably directly connected to the entrainment member 3 and through a tansmission to a further variator 30, e.g. of the type with variable pitch palley, to drive the entrainment member 2 through a drive shaft 31.
  • a speed variator 28 for the entraining rollers 6,7 which has an output shaft 29 preferably directly connected to the entrainment member 3 and through a tansmission to a further variator 30, e.g. of the type with variable pitch palley, to drive the entrainment member 2 through a drive shaft 31.
  • both the motor 21 and speed variators and deflector drive 30 may be provided with speed detector members 32 which enable an instantaneous and continuous measurement of the speeds of the various rollers to easily effect adjustment operations even with no fabric being fed into the machine; this allows an efficient and easy control of the absolute speed of the teaseling rollers, which is practically impossible to do with conventional teaseling machines because no suitable measuring instruments are accessible to measure the absolute speed of the teaseling rollers by adding together the rotation and revolution thereof; the operation would in fact be excessively complicated because related to too many variables among which the belt stretching, slippages, or non-constant drive ratii.
  • the teaseling machine operates in the following manner.
  • the fabric 4 is fed in from the side of the entraining member 2, and after travelling through the passage zone 5, comes out of the machine from the side of the entraining member 3.
  • a speed differential between the cited entraining members allows the tension on the fabric at the passage zone to be changed.
  • the teaseling rollers are rotated, e.g. by means of the motor 21 which drives the speed variators 23 and 24, and turn preferably in the same direction at an independently adjustable peripheral speed for the with-the-pile and against-the-pile rollers.
  • Their drive may ]be any one, e.g. directly from the motor 21, by preferably using the expedient of rotating the brushes of the with-the-pile rollers in the opposite direction to the brushes of the against-the-pile rollers so as to ensure in both cases rotation in the same direction as the tips of the metal hooks attached to the liners 10.
  • the brushes being carried rotatably on the brackets 13 may be switched from with-the-pile roller cleaning to againet-the-pile roller cleaning and vice versa while remaining for a longer time in engagement with those of the rollers which are more liable to clogging.
  • the brushes may be even omitted from the teaseling machine because, in these situations, clogging of the teaseling liners would not be a problem.
  • Cleaning of the rotary brushes may be accomplished by forced suction in a manner known per se.
  • the possible equipment of the machine with teaseling rollers having ribs as shown in Figure 5 further improves the teaseling effect to be obtained for a given teaseling rate; the ribs, in fact, impart to the fabric a vibrational stress which may be substantially likened to that created by the diverting rollers of conventional teaseling machines.
  • the clutch devices present on the output shafts of the speed variators provide a simple means of deactivating the moving parts to permit adjustment of the machine even wiht the fabric stopped and in the possible event of breakages.
  • the materials used as well as the dimensions may be any selected ones contingent on requirements.
