It is "already a number of ongoing pressing processes for a tape or strip material has been proposed for continuous production of products by means of pressing, and in 'one of the known older processes * whereby a belt or Strip of material to be processed was processed continuously as the material is fed, was a great skill required in terms of the uniform supply of the material through the successive pressing stages at the first stage to the last stage; this skill was especially necessary when the material was from one Tape was delivered and it was difficult to automatically and safely feed the material into the device. If the material too Once entered into the press, it was subjected to a preload. When the material is machined on the dangling end had to be, it was possible that the stamps acted contrary to the norm, if such an end was not very precisely in the area positioned between adjacent steps. Some punches were designed so that there was no waste on the ejection side a press should cause, and if the extreme end of a Material strips had to be treated in such stamps, so the semi-finished product could not automatically both on the supply and moved on the discharge side of the press and consequently the material had to be entered by hand into the stage and through the successive pressing stages are performed, and also the pulling out the processed products had to be done by hand. Such a manual process was very time-consuming.

The invention is based on the object of providing a continuous pressing process for a strip or strip material create, which effectively eliminates the disadvantages inherent in the known methods, in particular with regard to the known continuous processes have been outlined above. Furthermore, the object of the invention is to provide an expedient To create apparatus for carrying out the method according to the invention and the continuous pressing process for

509810/0746

to improve a tape or strip material so that it is particularly suitable for the manufacture of a small number of identical products by means of a single set of upper and lower punches, ie for a process in which the frequency of bar change during operation is high . Furthermore, it is the object of the present invention to provide a continuous pressing process for a band or strip material which requires only a short set-up time for the pressing process in operation for each type of product and which does not require a high level of training and training period for the operator. The operational safety with the method according to the invention should be great, in particular it should be automated as far as possible, so that accidents are eliminated. Finally, the object of the invention lies in the fact to embody the method that stresses are avoided at the sliding pad, both at the front as the freely suspended rear end of the processed laterials to thereby prevent damage to the stamper, which at the occurrence \ ^r on tension on the sliding block would be unavoidable.

This object is achieved according to the method according to the invention in that after the processed in the last pressing step Unload product on the other soap at the end of the press is, a semifinished portion of the material remains standing between the upper and lower sterile stack units of the die group c is held that the semi-finished section from the rest Part of the material in one place at a distance from the feed side the stamp assembly is cut off, a with the Semi-manufactured material section connected section of the material "From a group of stamps protrudes that the group of stamps, soft the cut off semifinished section between their punches holds, by means of a punch changer is brought away from the press body su a Sternpelablage to be stowed in it to ground that afterwards when the stamp group is used again v / is to be grounded, this has been taken out of your store and from the otempelv / ociisler is brought to the press body, uj.i again

inserted into the ground that the front iind of a subsequent, through the press / leading material through a Butt joint is connected by welding or soldering to the adjacent end of the projecting Haterialabschnitts, the related to the semi-finished product section, v / elcher in the used punch group is held, and that the press is then operated in a continuous pressing process.

With regard to the device for carrying out the method, it has proven to be useful if an upper and a lower Stamp unit can be combined to form a stamp group, each stitching unit is a series of mutually aligned, has jointly actuatable stamps to which the material to be processed can be fed continuously and gradually is, and dai3 the stamp group is assigned a stamp changer is, each of which is a no longer required star group from the Press for one bearing and vice versa one for the following preflight cycle appropriate stack group transported from the warehouse to the press.

A simple fastening and thus a simplification of the construction results when the upper Steraoeleinheit means Clamps on a sliding jaw of the press and the lower punch unit can be attached to a die frame of the press by means of clamps is.

Furthermore, it is very advantageous if the press, on the one hand, has a separating means for separating the material web from one from the stacking group of materials and on the other hand has a connecting means for connecting a section of material protruding from the group of stamps to the The beginning of a subsequent web of material that the release agent in the transport direction of the material in its working position or can be moved into its rest position so that the connecting means transversely to the material transport direction into its working position or can be moved into its rest position, and that the working

The stamp group or arrangement D with the material sections 3a and 3b held therein is then made by a hc-r Stamp changer 7 removed from the processing zone by any suitable drive means, not shown is driven and the punch group to the Sterripellager 8 carries, v / o the stamp group D is stowed together with other similar stamp groups, .which for production different types of pressing operations are used and similar ones are used i-sections of material protrude.

If so desired, a special type of item according to the one who raises one of the various stamp groups D stowed in the store 8 can be produced, the appropriate stamp group D for the desired product product selected. The selected stamp group D is accepted Lind conveyed by the punch changer 7 to the press zone, where the upper and lower stamp units 1 and 2 of the Storapel group D clamped to the sliding jaw S and the Hatrizenrahinen B each will.

Since, as mentioned above, with the semi-finished section 3a connected portion 3b protrudes from the punch group D when the punch group D is seated in the nipping zone, becomes the connecting means 6, which is now outside the connection position, as shown with the solid line, to the with dashed lines. moved position to the rear or inner end of the protruding 1-Iaterialabschnittes 3b with to connect the leading volume of the material 3, which in the V / ar was left near the nip in the previous cutting process. The press will wake up the connection process operated to start the above operation to sequentially manufacture the selected type of products.

As described above, the present invention various types of die arrays D with semi-finished product material portions 3a "and projected portions are in accordance 3b is stored in the deposit 8, and a special stamp. ¹ 509810/0746

The group type is selected from the pre-stored groups of stamps if it is required to produce the product that must be pressed with the particular group of stamps selected. The selected Ster.ipelgruppe D is arranged in the pressing zone, the upper punch unit 1 and the lower punch unit of the punch group being clipped to the sliding jaw S and the die frame B, respectively. Thereafter, the projecting portion 5b is connected to the leading edge of the following material section, whereupon the pressing process for the production of the selected product type is ready to start. Thus, the preparatory process can be carried out in a short time without the need for highly skilled workers, as are required in conventional corresponding presses. In addition, the possibility of chance, which can occur with the manual feeding of γόη material in conventional presses, can be effectively prevented. Furthermore, since the portion of the material lying in the press zone is completely pinched between the upper and lower otenpel units while the material is being processed, the material is not subjected to any preload load. it is initially processed and held in the stamp group and then the free end of the material is processed, thereby eliminating the possibility of damage to the stamp, which is otherwise unavoidable. The procedure.! The present invention can be used in a particularly advantageous manner when a small number of identical objects are produced in one pressing cycle and when the resistance of the stamps is great.

While in the foregoing only one embodiment of the invention has been inclined and described in detail, before it applies Cior. i that this has only been done for the purpose of illustration "wvi is not to be inherited as a definition of the invention or as a limitation"loc;".
