description

The invention relates to a method for equipping Textile items of goods in particular provided with a collar and for parts of vests, sweaters or the like. Knitwear certain pieces of goods, of which at least two individual or from one behind the other with meltable Separating threads to form strands of goods sewn together are connected by means of pallet loops lying next to each other, this group of goods is damped in a transversely tensioned position and the drop stitches running in the longitudinal direction be severed again and a device for performing this method.

Textile sections for sweaters, vests or the like. Knitwear, which after equipping will be anunenaenäen, are usually provided with a collar. To equip them not individually by the relatively wide D. "nnf ~ To allow machines to run, two or more pieces of tessile are made into a group by means of drop stitches connected and, if several such groups are connected one after the other, this is done by means of fast-capable Separating threads. The connection of these sections can already be done in the usual way during their manufacture accomplish. So far, such a group of goods has been introduced into a damping and separating device for equipping, so it is used to prevent it from rolling in on it Edges and a wrinkle or wool formation seized from the side and stretched in the transverse direction. This would also include the Bundles captured and pulled out to the width of the sections. A strand of goods formed in this way is then considered to be continuous pale wide area in a steaming device

leads to be dampened, shrunk, smoothed and shaped. If the heating is sufficient, they will also melt the possibly existing separating threads and the groups of pieces are separated from one another. The lateral connection the pieces are then loosened by cutting open the drop stitches. Here it turns out, however, that the individual sections no longer take on the desired shape. Especially the bundles of the cuts that are under after increased stretching, which have been dampened and thereby fixed, no longer return to their original shape and usually have to be assembled again before further processing.

The invention is therefore based on the object of a method and to propose a device for equipping pieces of textile goods with a collar so that the The shape given by a covenant is also retained on equipped pieces of goods.

To solve this problem, the method of the type mentioned according to the invention is characterized in that that the group of items of goods stretched to a predetermined width in the transverse direction is still in the tensioning field along the fall- ^ mesh is separated and only then the so separated pieces of goods are steamed and with melting of existing separating threads ready to be equipped.

Pieces of goods treated according to this method can, for example, move along the drop stitches after being separated by cutting the drop stitches, develop back into the desired shape and essentially free of tension, nevertheless, however, are introduced into the damping device in a laid flat, extended position, in which the items of goods are then and their shape can be dampened, smoothed and fixed.

By disconnecting it beforehand, it will be easy to reconnect Get well-shaped and congruent pieces of goods.

An advantageous device for carrying out the method is characterized in that near the end of the passage A clamping field aligned with the drop stitch lines cutting devices are arranged on both sides Each cutting device is provided with a hold-down device for the cut edges of the pieces of goods and the the transfer belts adjoining the hold-down devices reach over onto a transport cloth of a damping and separating device.

The cutting device is advantageously formed by a circular knife, which is one of the pieces of goods to be cut is assigned to overflowing cutting shoe.

With a cutting device designed in this way, strands of goods or webs of goods can be processed at a high throughput speed Cut lengthways along the existing drop stitches and split the partial strands or pieces can then enter the damping and separating device immediately. The hold-downs are used to cut the Edges of the strand of goods continue to be guided and held in place.

In order to keep the rope to be cut under constant tension and this transverse tension directly to be picked up again after cutting, lateral i \ uf- · needle chains equipped with needles pointing downwards are provided.

In order to align the lengthwise cutting of the Uarenstrnges exactly to the drop stitch lines, a straightening device is connected upstream of the cutting device, which controls the drop stitches by means of an optical scanner and controls an upstream aligner accordingly via pulses.

Further features of the invention are set out in further subclaims claimed.

pieces loaded and thus worked more economically will. The strand of goods to be equipped is first fed through shrink brushes and onto needle chains running laterally 7 automatically needled. Because the needles of these needle chains are directed downwards onto a transport cloth 8 are, it is possible to guide the rope tightly and without sagging over the transport sheet. Of the The rope and thus the pieces are stretched to a predetermined width in this tensioning field. A reinforced one The bundles, which consist of a firmer but also more elastic knitted fabric, are stretched and in the original shape towards the center are more contracted than the other parts. The needling of the rope of these needle chains takes place downwards and only after the lengthwise cutting immediately before the outward run in the subsequent damping and separating device, so that the goods are taken over without warping or curling the edges will. The strand of goods can be untreated, i.e. only stretched in width and tensioned by the cutting device are fed. On the other hand, there is also a pre-muffling possible before cutting, provided that this should be advantageous for the pieces of goods to be won, for example for items made of acrylic thread.

The finishing machine shown in Figures 1 and 2 has two cutting devices 5 between the two Needle chains 7 equipped. This means that the strand of goods can be divided into three partial strands by two longitudinal cuts. If there is a line of goods or a group of goods from two or more than three pieces sewn together, then either one or more cutting devices to make the separation into the grain sections along the falling pocket lines.

The optical scanner 22 of the straightening device 21 is of a known type. By means of a light beam, it controls the snapping of the approaching ^T \ ^T arenstrange. For this reason, a recess 34 is provided in the cutting shoe. The scanner can also be attached to the support block 25 by means of a support arm 35 (FIG. 3). In order to set it up, on the other hand, it is also supported on the support tube 36 which is arranged transversely above the clamping field and on which the straightening wheel 23 is also supported by means of a linkage 37. This straightening wheel is driven by a control motor 38 which responds to the pulses emitted by the scanner and the Richtrar! more or

less far either in the one or in the ancl «rfi Direction turns. The straightening wheel is therefore in the Axis of rotation 39 running in the direction of movement of the strand of goods can be rotated to both sides. It's on the surface 40 of the underlying ^ chnp.idschuhes about perpendicular. For precise setting up and, above all, for moving the straightening wheel, there is a further transport tube 4 2 another support roller 43 of the straightening wheel rod. freely movable attached.

posed. This aligner consists of two straightening rollers 50, 51, about 10 to 25 cm in length, arranged one behind the other in the direction of transport of the strand of goods, which are mounted in a housing 52 by the axes 53, 54. Above these straightening rollers there is a pivot axis 56 in the housing about which the housing with the two straightening rollers can be rotated. Therefore, each of the straightening rollers can change its distance from the transport cloth or the Viaren strand. In the normal position, they are at a distance above the transport sheet and the one lying on it. Fabric rope, so that they do not touch iarenstrang the ^T in this position. The two straightening rollers are also arranged in front of the inlet end of the cutting shoe. The running surfaces of the straightening rollers have threads or the like. Screw grooves that run in opposite directions, e.g. 3. that of the straightening roller 50 to the left and that of the straightening roller 51 to the right. If the incoming strand of goods is now to be moved either to the left or to the right according to the scanner pulses that result from the drop stitch to be aligned with the circular knife, either the straightening roller 50 with the left-hand thread or the straightening roller 51 with the right-hand thread is used brought and for this purpose rotated the housing about the pivot axis 56 either counterclockwise or clockwise until the desired straightening roller runs up on the rope. To initiate this rotary movement, a pressure cylinder 58 is provided, which acts on its piston rod 59 on the housing 52 and rotates it with the straightening rollers in the desired direction. The pressure cylinder 58 is actuated by the scanner, which emits the pulses for this purpose. The two straightening rollers 50, 51 are still driven by means of a drive belt 60. Contributing their axes 53,54, the pulleys 61 and 62. The drive is effected by a gear motor (not shown) via a Ahtriebscheibe 63, Suitably the _w gear motor between about 150 to 350 revolutions / minute continuously adjustable, a wide adaptability to to have different working speeds available.

The straightening rollers rotate in relation to the point of contact, in the same direction as the strand of goods. With powered With straightening rollers, the strand of goods can be aligned more evenly and better and fed to the circular knife. A sideshift to the left or to the right to be exerted on the strand of goods is particularly effective, when the straightening rollers rotate at a speed that exceeds the transport speed of the rope. This aligner, which consists of these two straightening rollers, is supported by means of an axis 56 which supports the axis of rotation Support rail 66, to which the pressure cylinder 58 is also attached, can be removed from a support tube 65 crossing the clamping field attached.

Unless the transport sheet 8 of the clamping field is divided lengthways is and therefore a holder of the cutting shoe from below or from the side between the transport cloth and strand of goods is not possible, the circular knife axis 11 can be used as a support element for the cutting shoe to serve. On both sides of the circular knife support supports 80 are mounted on the axis, one of which can be screwed onto the cutting shoe Carrying support plate 81. The hold-down devices (FiT. 3) with their pressure belts rotating around the rollers 17, 18 20 are held on the support block by means of support arms 83, for example. Legs 84 of these support arms are used for Laqreruncf the roller axles and their spacers. The drive the pressure belts can be derived from a higher geared drive shaft (not shown).

If the existing support tubes 36,42,65 bsv. other Hanger for the straightening device and / or the aesante cutting device cross the entire span, several devices can be attached next to each other. In this case, the cutting devices can be adjusted to a specific one as required Slightly move the cutting line or to the width of a path. Cutting and straightening devices are then expediently
