Manufactured by GrnbH&C00KG,) r7
In the case of the known cloth spreading machine, a cutting device is provided on the sheet spreading carriage for cutting off one layer of the H material spread from a separate supply source for the flat/C phase. There is. The cutting device has a cutter carriage horn that is driven and provided with a sharpened cutter disk. The cutter carriage is guided over the spreading carriage in order to move the cutter carriage across the longitudinal direction of the web-like material to be spread. It moves back and forth.

A second electric motor located on the cutter carriage serves to drive a cutter disc which is driven along one edge of the support surface of the spreading carriage supporting the spreading material. is moved and thus can cut off a layer of rolled material from a source of material in the direction of movement of the force ivy carriage. In this method,
Significantly, it is not necessary to replace the carriage of the cutting device after the cutting has been made and before continuing the spreading of the material. This is due to the tube cost of modern spreading machines,
This helps to rationalize the operating time of the machine, which is important in terms of the high energy required to operate this type of spreading machine. However, on the other hand, the cutter disks of such cutting devices must be relatively sharply ground.

A so-called ski-roller type cutting device called B5 is known, which is equipped with a disk-shaped squeegee roller in place of a cutter disk. The squeegee roller presses its circumferential edge against the support surface for the web-like material to be cut. The support surface is formed by a bar, so that the material to be cut is compressed under high pressure and cut.

In order to generate this compressive cutting pressure, cutter galley
Zo has a means of reciprocity that can be used for all parts. This carrier means is connected to the ski and slider roller bearings of the cutter carriage via a crosspiece arranged behind the skies roller in the cutting direction. Therefore, the part forming the support surface for the material to be cut is not deformed by the pressure of the squeegee roller. With this known squeeze roller cutting device, it is no longer necessary to sharpen the cutter disk, and the squeeze roller can be easily replaced every few months. However, on the other hand, this like...
Roller cutting devices have the disadvantage that they can only cut when the cutter is moved in one direction by means of the carriage crosspiece supporting the carrier means. For this purpose, after the cutting device has cut a layer of rolled material, it must first be returned to its original position before the spreading procedure can be continued. It should be noted that since the holding bar or the squeeze roller that rolls over the flat material to be cut does not require any driving force, the squeeze roller type cutting device has the advantage that it does not require any motor other than the motor that drives the carriage.

OBJECTS OF THE INVENTION The present invention has the simplicity of a squeeze roller cutting device and has the advantage of having the simplicity of a squeezing roller cutting device [7] until the cutting device is returned to its starting position 14 after one layer of the expanded material has been cut. Eliminates the disadvantage of not being able to perform paper work (cutting equipment for a spreading machine)
<Structure and effects of the invention> The present invention spreads a flat web-like material in layers on a spreading table using a spreading gear ridge that moves back and forth along the spreading table. In the spreader, a cutter carriage equipped with a squeegee roller reciprocates across the longitudinal direction of the web-like material being spread on the spreader carriage, and the cutter carriage is reciprocated across the longitudinal direction of the web-like material being spread. A support surface for the nib-like material is provided, and the support surface is raised so that the squeegee roller rolls, and the support surface is provided with a cross disposed behind the squeeze roller when viewed in the direction of the cutting force. Let us imagine a spreading machine supported by a support means connected to a receiving part of the ski-flora 41 of the force vine carriage using a piece.

The object of the invention is achieved in that the skier and rollers are arranged on the cutter carriage on both sides of the crosspiece in the running direction of the forceps.

In a preferred embodiment of the spreading machine of the invention, a particularly high compressive cutting pressure is achieved by having a retaining roller for the supporting surface opposite the supporting means or the squeezing roller bearing. The supporting surface is formed by a bar, at which said retaining roller is fixed in a direction perpendicular to the longitudinal direction of the bar by two flanges spaced apart at a distance corresponding to the width of the bar. It is preferable to have a cutter carriage in which the direction of force perpendicular to the direction of movement is guided by n.

The cutting device of the spreader of the present invention has squeegee rollers disposed in front of the cross piece supporting the carrier means in each direction of movement of the cutter carriage. It is possible to cut with this cutting device, and it is possible to eliminate the waiting time required at the cutter carriage, which has to return to the starting point.

<Embodiment> Other features, advantages and details of the construction of the present invention will be described below with reference to the attached drawings showing a preferred embodiment of the spreading machine of the present invention.

FIG. 1 shows a sheet spreading carriage 1o of the invention (21), which can be reciprocated along the sheet spreading table 12 by a driving means shown in FIG. 7j<L. The spreading carriage is equipped with a supply roll 14, from which the web-like material 18 to be spread is pulled out by a pull-out roller 16 driven in accordance with the speed of the spread carriage. - As shown in cross section in FIG. 3, the tube-like material barb 18 enters the funnel 20 from above through a deflection arm supported by the spreading carriage lO, and almost horizontally enters the funnel and therefore the spreading gear ridge. Leave f'L. The web cutting material is therefore guided over the almost horizontal support wall 22 forming the lower end of said deflection channel. In this way, as the spreading carriage 10 moves from right to left in FIG.
The sheets are placed on two sides of the spreading table 12 or on other layers of web-like material already spread on the spreading table.

The deflecting funnel 20 is integrally constructed in the spreading arrangement device 26 of the spreading carriage 10.

The rolling and arranging device 26 is preferably constructed such that it moves upwardly as the thickness of the pile of the plurality of material layers to be rolled increases. For this purpose, guide rails 28 for the rolling arrangement device are provided on the rolling carriage 10.

In front of the deflecting funnel 20, the spreading arrangement device 26 has a pivot shaft 30 for two pivot arms 34.

The clamping par 32 is supported by the two pivot arms 34), so that the clamping par 32 is moved counterclockwise about the pivot shaft 30 outside the operating position shown in FIG. can be turned to In the position shown in FIG. 3, the flapping bar 32 presses the web-like material 18 to be spread against the support wall 22 and securely fixes it in that position. The web-like material 24, which has already been rolled out, is then cut off from the rolled web material 18 by the action of a cutting device 38 supported by the spreading arrangement device.

The cutting device 38 is basically fixed to the cutter carriage 40 and the sheet spreading arrangement device 26'i1. The drive motor 46 includes a guide par 42, a support par 44 arranged in several cases on the support wall 22, and a drive motor 46 with an attached gear device. The cutter carriage 4° can be reciprocated across the longitudinal direction of the rolling table 12 via a motor, gears and toothed belt 5o.

The toothed belt 50 includes a gear 52 shown in FIG. 2, and another free-rotating gear (not shown) located in front of the sheet spreading arrangement device 26 in FIG. Do not let it run for a long time.

As shown in FIGS. 2 and 3, the cutter carriage 40 has two grooved guide rollers 54 running on the guide par 42 in its upper portion. The cutter carriage also has a cross piece 56 in its central part, to which is screwed a carrying means 58 for supporting the support par 44.

This carrier means has two rotatable holding rollers 60 by which it is guided on the support bus 44. For this purpose, the holding roller 60 has a housing flange 62 at its respective end, which flan 2 acts as a guiding means on one side of the longitudinal edge of the support par 44. The carriage 40 has two elongated holes 66 extending in the direction toward the holding roller 60, and the distance between the two elongated holes corresponds to the distance between the axes of the holding roller 60. The shaft body 70 is slidable in a direction substantially perpendicular to each of the elongated holes, and is supported by the shaft body 70, and the skewer roller member 7 is supported by a hoop bearing 72.
4 is attached to the shaft body 70. The squeezing roller member 74 includes a threaded edge 376 with a strut collar 76a, a threaded gear horn 78 screwed into the pusher 76, and a squeeze disc 80. The squeeze disk 80 is constructed to be inserted between the threaded pusher 76 and the threaded cap 78, so that it can be attached replaceably. Skies disk 80 is supported) vs. 2-44! - Press +t to remove. For this reason, when pressing with a thread, the pin must be on the other side.
'L' shaft 70 and the shaft 70 are inserted into the threaded hole 84 of the cutter carriage 40. It is used to advance the squeezed disk 80 toward the support bar 44. Therefore, the squeeze discs 80 can be adjusted individually, and the holding roller 60 is always located at the lower blade immediately at the point where the corresponding squeeze disc is pressed against the support bar 44. Therefore, even if an external force is applied to the squeezing disk, it is impossible to move the squeezing disk away from the support bar 44.

The cutting effect of the cutting device [38] is affected by the sharp dust on the cutting edge and is affected by the pressure with which the squeegee disk 80 is pressed against the support bar 44, so the skinny roller is No need to have any sharp cutting edges.

In each direction of movement of the cutter gear 40, the two skinny rollers 80 are tilted or one of them is in front, so the cutting is performed by the cross piece 56 holding the supporting means 58.
The cutter carriage 40 can be moved in every direction regardless of the direction of movement.

It should be added that the orientation of the cutting device is, of course, unimportant. As a result, for example, even vertically suspended web-like materials can be cut with this cutting device. In this case, the support par 44 is vertically
The skies disk 80 is then placed horizontally.
