Abstract

Provided is a device (10,11,12) for capturing fiber slugs in a fiber net forming machine, comprising a roller (10) and systems (11, 12) and used for capturing and leading again redundant fibers.

Description

Catch yarn feeding device

Technical field

Having on the machine that forms fibroreticulate roller shape workpiece by staple fibre, for shredding and homogenising, use cylinder or the cylinder that is provided with accessory usually, it is called work-stripper roller (Arbeiter-Wender).Referring to DIN 64118.

Background technology

In this machine, worker rollers batches particularly fibre bag of fiber from cylinder or cylinder, and sends it to stripper roller, and stripper roller flows to roller with it again.If carry the fibrous batt that has slubbing for the fiber web lapper, then when fiber process fiber web lapper, this slubbing is elongated by worker rollers slightly, but can not eliminate fully.This fiber web is inhomogeneous, seems " clouding is arranged ".

Summary of the invention

The objective of the invention is, propose a kind of device, it can improve the fibroreticulate uniformity, and needs less work-stripper roller.

Though known fiber net lapper suction everywhere fibre down and these fibers are returned, for the wool draft machine, be well known that, utilize the burr-crushing hired roughneck to destroy bur from cylinder along working width, become waste material then.For flat card, utilize revolving flats in large area from cylinder output staple fibre and dirt, and flow to waste material.When making fiber web, these measures are not adopted so far as yet.In these external these methods, people attempt to cut off up hill and dale unwanted part.Catch with regard to the yarn feeding device with regard to of the present invention, do not hope, be used for handling and realizing fibroreticulate homogenising but carry again fibre cutting.

A kind of special embodiment of catching the yarn roller is the roller that has different-diameter along the working width of roller.This is favourable, if hope special moulding to fiber web to be set, for example the edge is thin or thicker, and the perhaps thickening gradually towards the center is so that improve subsequent treatment.

Realize similar effect mode can for; According to claim 7) with 8) press down parts unlike cutting knife 13) such all identical at a distance of the spacing of cylinder along working width; But having an edge, this edge changes along working width at a distance of the spacing of fiber being carried out the roller of follow-up delivery.This also can carry out through the segmentation of cutting knife, and the spacing of each cutting knife section is manually perhaps regulated through control member.

Description of drawings

The present invention will set forth by means of Fig. 1 and 2.

Fig. 1 exemplarily illustrates the fiber web lapper;

Fig. 2 illustrates uniform machinery, and it also is equipped with outlet roller.

The specific embodiment

Fig. 1 exemplarily illustrates the fiber web lapper.Fibrous batt 1) through so-called feeding roller to 2) flow to licker-in (Vorrei β er) 3).Utilize transfer roller 4) deliver to master rotor 7 to transmitting fiber tow) on.Round master rotor 7) be provided with worker rollers 5) and stripper roller 6).Doff (Doffer) accesses fiber and forms fiber web.Unwinding device 9) takes off this fiber web from doff.

In this sketch, use the slubbing that a) is illustrated in fibrous batt feeding mouth place, use b) be illustrated in the slubbing that is elongated in the debatching of fiber web lapper.Worker rollers 5) and stripper roller 6) elongate slubbing and flatten.

Fig. 2 illustrates uniform machinery, and it also is equipped with outlet roller 10), this outlet roller is caught excess fiber, and be sent to compile position such as funnel 11).These fibers are aspirated through aperture 12), the fibre stream that forms fibrous batt directly automatically flowed to again by output equipment.This outlet roller also can be installed in other roller or the cylinder place of machine together with aspirating mechanism, for example is installed in master rotor or work-stripper roller place.For example also can be configured to outlet roller to stripper roller, its mode is that it is not to give the cylinder corresponding with it 7,3 with transmitting fiber tow, but gives air-flow or conveyer belt with transmitting fiber tow.Importantly return, repeatedly present in case of necessity the fiber that has returned to web material output, those excess fiber of producing inhomogeneities automatically along working width.Correspondingly; Outlet roller and licker-in 3) be adjacent to arrange; Perhaps transfer roller 4) arrange towards master rotor or home roll from licker-in, perhaps with master rotor or home roll 7) be adjacent to arrange, perhaps with worker rollers 5) or stripper roller 6) be adjacent to arrange; Take off fiber from these rollers thus, continue the major part of conveying fiber then by cylinder corresponding or roller with outlet roller.Sketch a) and b) be illustrated in fibrous batt and the fiber web after machine before the machine.

Before fiber arrives outlet roller, be preferably in the somewhere installing with respect to roller 4) adjustable parts 13 that press down).

Outlet roller advantageously has the accessory of band neutral angle or negativity anterior angle (Brustwinkel), and the fiber that has taken off breaks away from swimmingly in outlet roller thus and can not twine.Turning to of outlet roller with identical with turning to of its corresponding roller that takes off fiber or cylinder.Its peripheral speed be roller corresponding or cylinder with it peripheral speed 0.6-2.0 doubly, but preferably be higher than the peripheral speed of roller or the cylinder corresponding with it.

Claims

1. the device that is used for a kind of machine, this machine forms fiber web and has at least three rollers, and said roller is preferably provided with sawtooth or pin rod; This device comprises at least one outlet roller (10; 6) and return mechanism (11,12); Outlet roller (10; 6) can with the roller (3 that forms fibroreticulate machine; 4; 5; 6; 7) be adjacent to arrange, and take off the fiber of the web material that forms inhomogeneities, flow to return mechanism (11) to the fiber that takes off from forming fibroreticulate machine along the whole working width of one of roller or part working width from this roller; Return mechanism (11,12) can with form fibroreticulate machine and be connected, the fibrous batt that makes the fiber that takes off flow to machine in formation need not subsequent treatment before and can be transferred to wanting fibre treated again.
