Definitions
- the invention relates to metallic guiding devices for guiding fiber material between the winding rollers and a belt deposit of a comber.
- Such guiding devices are known in a comber between the winding rollers and the tape storage.
- the cotton unwound from a cotton roll lying on driven winding rollers is introduced into a forceps unit via a guide plate. That from the pliers to the
- the combing process to a subsequent pair of tear-off cylinders delivers fiber material via a fleece guide plate via a pair of draw-off rollers to a subsequent belt table, on which it is now in the form of a belt.
- the combing machine is equipped with eight combing heads, each of which delivers a sliver onto the subsequent belt table.
- the slivers are transferred via the belt table to a subsequent drafting unit, in which the slivers are stretched and combined to form a sliver.
- This fiber sliver is also transferred to a pair of calender rolls via corresponding guide devices, via which it is deposited into a can via a funnel wheel of a sliver storage device.
- the fiber material On the way of the fiber material from a roll to a tape storage, it is guided over several guide devices which are not driven. This can lead to malfunctions, in particular if the fiber material is electrostatically charged due to friction or the fiber material has sticky components such as honeydew.
- the disturbances in the transport of the fiber material can occur at various points between the winding rollers and the tape storage and are also dependent on the shape (cotton, fleece, tape) of the fiber material.
- the transport of the fiber material is susceptible to disruption with respect to the above-mentioned criteria if it is in the form of a fleece. This shape is present when the fiber material is discontinuously discharged onto a subsequent fleece guide plate via the front pair of tear-off cylinders.
- conventional combers contain tear-off cylinders mounted in a machine frame, usually two pairs, which are rotated back and forth with a pilgrim step movement during operation of the comber.
- the tear-off cylinders form a combed machine comb from successively fed, combed fiber beards and deliver this to a fleece guide plate, which guides the fleece to a pair of draw-off rollers also mounted in the machine frame.
- the take-off rollers rotate continuously at constant speed during operation. Since the tear-off cylinders are rotated back and forth as already mentioned, the fleece forms waves on the fleece guide plate.
- the object of the invention is to design the fleece guiding devices specified at the outset in such a way that disruptions in the transport or the transfer of the fiber material between the winding rollers and the belt deposit of a comber can be avoided as far as possible.
- This object is achieved in that it is proposed that at least one of the guide devices is provided with a surface coating comprising nanoparticles, which reduces the adhesion of fibers.
- nanoparticles are designed accordingly (e.g. nanotubes with electrically conductive inclusions).
- the nonwoven guide plate immediately following a tear-off cylinder pair is at least partially provided with the surface coating containing nanoparticles.
- the surface coating consists of a sol-gel layer that contains crystalline particles in an amorphous hardening solution. Furthermore, crystalline nanoparticles can be contained in the surface coating, which increase the abrasion resistance and scratch resistance, or which achieve the non-stick properties through a microstructure - also called lotus flower effect.
- fluoropolymers such as PTFE, FEP, PFA or ETFE can additionally be contained in the surface layer.
- the surface coating can be antistatic or electrically conductive. As a result, electrostatic charging is largely prevented in the first case and, in the second case, any static charge that may be present is dissipated via the surface coating.
- Fig. 1 is a schematic side view of a combing head of a comber with a fleece guide plate.
- FIG. 3 shows a schematic top view of a comber according to FIG. 2
- FIG. 1 shows schematically a combing head K of a combing machine 1 with winding rollers WW on which a cotton roll W rests for unrolling.
- the fiber material in the form of a cotton wool WT is fed to a pair of pliers Z, which, when the
- the combed end of cotton wool (also called fiber beard) is presented in the front position shown in FIG. 1 with the pliers Z open to a subsequent pair of tear-off cylinders 2 for soldering to the previously formed fleece.
- the pliers Z open to a subsequent pair of tear-off cylinders 2 for soldering to the previously formed fleece.
- two successive tear-off cylinder pairs 2 are shown, in particular that the pair of tear-off cylinders immediately following the pliers Z is responsible for the tear-off process and the soldering process.
- the front tear-off cylinder pair 2 is followed by a fleece guide plate 3, a draw-off roller pair 4, a funnel 5, calender rollers 6 and a belt table 7.
- the fleece (not shown) discharged from the front tear-off cylinder pair 2 onto the fleece table 3 is combined into a band by the funnel 5 and by the calender rolls 6 placed on the belt table 7.
- the fiber slivers FB deposited by the respective combing head K on the belt table 7 are, as shown schematically in FIGS. 2 and 3, transferred to a drafting device S and stretched there and combined to form a single fiber sliver (not shown). This sliver is transferred to calender rolls KW by means of appropriate guide means and stored there in a can KN via a funnel wheel.
- the fleece When the tear-off cylinder 2 is advanced, the fleece arranges as a surplus in the fleece guide plate or fleece bowl 3, and when the tear-off cylinder 2 returns, it is drawn almost smoothly again.
- the fleece guide plate 3 thus acts as a fleece calming zone.
- the fleece is combined on the fleece guide plate or fleece bowl 3 or in the zone thereafter. This can be done centrically or eccentrically, as has been the case with the combers in recent decades.
- the funnel 5 being arranged in the middle of the fleece bowl 3, the soldering lines form an arc and lead to a pronounced development of the combing or soldering periods.
- a fleece key 3 provided with a plastic coating has no advantages over the conventional fleece key made of a metal sheet such as, for example, stainless steel sheet.
- a surface coating composed of a layer based on sol-gel with a glass-ceramic basic structure, as a result of which the fleece bowl 3 has a surface that repels sticky contaminants.
- honeydew and fibers contaminated with honeydew in the fleece then no longer adhere to the fleece guide plate 3.
- the layer can additionally contain fluoropolymers such as PTFE (polytetrafluoroethylene), FEP (Fluorinated ethylene propylene polymer), PFA
- the surface coating contains crystalline nanoparticles which increase the abrasion resistance and scratch resistance.
- the non-stick properties in particular can be achieved by means of a microstructure (lotus flower effect), which also improves the transport properties of the nonwoven guide plate.
