According to one aspect of the present invention is a machine has been created, which is intended when applying a wtüclcs tissue-like material on a separate .'Jt if to be used, this device having a pair of draw rollers defining a draw nip, also a pair of laterally adjustable brush wheel / press shoe assemblies, and also an execution for rotating the Pull rollers and the brush wheels.

When using the device to "overfeed" the Material or for the delivery of an excess of material on a Gtiftrahmen the known principle is different Material feed speed (linear singing speed) compared to the material uptake on the Ctiftrahmen (linear output speed) used, whereby the tension gap takes up the substance or the material from a storage pack or a 3all or a spool, preferably over its entire width, but possibly only at its edges or fabric strips, and it introduces between the brush wheels and press shoe arrangements, which are arranged close to the delivery side of the draw nip. While the size of the track width of the column gap is the maximum The width of the material that can be fed through the gap is limited by the pair of brush wheels and the associated ones Press shoe arrangements, as mentioned, spatially adjustable relative to one another, while they are quite a part of the tension gap construction, so that before a given Piece of material is fed through the tension gap, the pair of brush / press shoe assemblies is adjusted with respect to each other, so that the edges of the through the tension gap passing material align with the outer edges of the brush wheels.

It is a feature of the present invention and is available in Contrary to industrial practice that the material is transferred to a pin frame that is held by the tension gap arrangement is completely separate.

The draw rollers Ιο, 11 and the brush wheel / press shoe pairs 13, 14 are expediently mounted on a base frame (not shown), their drive being an electric motor can that sits on this base frame; however, the drive can also be combined on the part of a not shown Calender machine take place, which has a roller driven by an electric motor, from which a belt drive 18 is removed is and drives an inclined or conical pulley 19 on a Singangswelle 2o, which is a stepless Control gear 21 is assigned. The latter is a conventional bevel gear with two opposite each other arranged, tapered pulleys 22, which are connected to one another by an endless belt 23, under the action of a sliding nut 24, a spindle 25 and a handwheel 26 along the tapered pulleys 22 can be moved »

The pin or mandrel frame will now be described below will. In the embodiment shown, it has the shape of a reel with an axle shaft 27, which carries two disks 28, one of which is displaceable along the axle shaft 27 for the purpose of adjusting the width, as explained below. Alternatively, both disks 28 can be moved along the axle shaft 27. the Axle shaft 27 is hollow and provided with openings, as indicated at 29 in FIG. 2. At four angularly in equal At a distance from each other arranged points of each disc 28 is a respective approach 3o welded, each of which is provided with two sockets on its outer surface. The axially outer depressions of the lugs 3o of each disc 28 are used to assemble a ring 31, which is on the lugs 3d by means of screws or other suitable means with the ring carrying a series of pins 31A. The purpose of the axially inner sinks will be described later.

Sine of these disks (see Fig. 2) is fixedly connected to a sliding sleeve 32 within the axle shaft 27 and between zv / ei pressure sleeves 33 are arranged, between which a miter hood 34 extends rotatably and penetrates the sliding sleeve 32 and is in screw engagement with it. The miter hood 35 has near the open end of the axle shaft 27 a head 36. Turning the screw 34 moves the sliding sleeve 32 and its washer 23 along the axle shaft 27 either in the direction of the other disk or away from it, in each case depending on the direction of rotation.

Thus, the pen frame is actually a width-adjustable reel that has one on each of its disks 28 Has pin ring 31.

The non-adjustable disc 28 has an adjacent one Gear wheel 37, which is firmly connected to the axle shaft 27

In order to apply a piece of fabric-like material to the pen reel, the latter is in slots of arms 38 removably mounted, which are arranged on the aforementioned base frame. The slots are made with any conventional one Means releasably closed, for example by means of removable caps, to prevent accidental leakage avoid the pen reel.

To make a transfer of material to the pen reel cause the brush wheels 13 to touch the base of the pin rings 31; however, there can be a setting for thicker fabrics be made.

The gear wheel 37 sits on a gear wheel 39 and is in engagement therewith. The gear wheel 39 is rotatably held by the adjacent arm 38 and by means of a special belt (timing belt) 4o by one of the

conical pulleys 22 driven. The other cone-shaped Pulley drives the nip roller 11 via gear wheels 41 and 42; a gear wheel 43 is also located the other end of the splitting roller 11 in engagement with a gear wheel 44 which is firmly attached to the axle shaft 15, which carries the brush wheels 13.

The handwheel 26 is calibrated so that its I divisions of the speed differences, which can be set on the bevel gear, + lo: S to -4o; S result in excess, i.e. the The pen reel may be driven faster or slower than the speed at which the hater is operating ial from the tension gap Io, 11 is delivered.

The ratio of the gear wheels 43, 44 is selected in such a way that the brush wheels 13 are given an advance of 50 to 50 % with respect to the nip roller 11.

Before tissue-like material is fed to the pen reel, the continuously variable bevel gear is activated by means of the handwheel preset to give the required amount of excess or otherwise} then the web material passed through the draw nip lo, 11, the press shoes and the brushes 13, 14 to exit at the point v / o the pins each Disc 28 press into brushes 13.

\} ± e already indicated, the pen reel is informed of a rotary movement. Thus, the material is transferred from the nip / brush wheel assembly to the pen reel to form a hollow cylinder of material on the pen reel.

The infinitely variable gear drive between the pulling gap and the pin roller provides a speed differential that creates an excess of material between the pins placed if necessary.

"above a number of different uses, where such a circular mold or I.'tifthrispel can be subjected to a variable length of material with a tab with a fixed Use pulley diameter.

Usually it will be most convenient to have a sexton To treat a sample of a ribbon, the length of which is approximately the circumferential length of a disk 28 is the same. In some In some cases, this length can be smaller than the circumference of the disc.

However, when using the lithium reel, it is also possible to to continue the rotation of the same after a complete rotation and thus also the winding up from further to continue limaterial in overlapping layers, in each case according to the thickness of the material used and the length of the pins used.

;, 'ie it is obvious, the transfer reel can can also be used to pick up or carry material without an excess of material occurring.

According to a modification or other configuration, the pen frame is rectangular and flat and has two opposite, parallel metal strips, each of which carries a number of pins and the one in theirs Width or in their distance from one another are adjustable, by any suitable means, for example through slots and locking screws or through adjustment using screw threads.

The lame is placed close to the brush wheels, whereby the relative movement can either be obtained by that the frame is caused to move away from the brush wheels in fixed positions, however

In any case, there is a setting of variable speeds between the linear speed of the material passing through the tension gap and the relative speed the train gap / pin frame speed for a differential speed ratio which, if necessary, provides an excess of material on the pins.

The two sides of the rectangular frame that are parallel to the axis of the tension gap do not necessarily have to be be provided with pins; solder the attached material If desired, attach yourself to other, suitable., iron there.

The web-like material can be fed to the draw nip in any convenient way, but it is preferred the tension gap Io, 11 by means of a combined dye / To feed calender device.

The pen reel with the material test piece attached to it can be inserted into a treatment chamber, to be exposed to treatments with liquid or gaseous media at atmospheric pressure or higher pressure, or even with a vacuum.

If necessary, a tube or a cylinder made of a mesh or a screen material can bridge the disks 28 or combine them with each other if materials are treated like a knitted fabric made of synthetic fibers, to avoid shrinking or shrinking in the otherwise unsupported center of the material cylinder.
