Abstract
Abstract An apparatus for a timed, settable working material feed in presses with a stepwise driven pair of first feeding rollers by the press by means of a step-by-step switching device, wherein the first feeding rollers grip the working material in a clamping manner. A first change gear drive having a coarse setting step and a correction- or fine-setting step is provided. The step-bystep switching device is operatively connected with the pair of the first feeding rollers by means of the change gear device. A pair of second feeding rollers, is also arranged and a second change gear drive for the pair of second feeding rollers, is provided. The first change gear drive is operatively connected with the second change gear drive, and the pair of second feeding rollers is disposed on the side of the apparatus opposite that of the pair of the first feeding rollers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
In a press having an upstanding stand, an apparatus for performing a timed, settable working material feed for said press, said press having a ram, and at least one drive means for said ram and said feed apparatus, said feed apparatus comprising a first pair of stepwise driven feeding rollers mounted on one side of said stand and a second pair of feeding rollers on the other side of said stand, intermediate drive means for said feed rollers, comprising a first change gear drive having a coarse-setting step to selectively set the amount of a basic feed and a correction or fine-setting step to selectively provide a fine adjustment of said basic feed, said step-by-step switching device operatively connected with said pair of said first feeding rollers by means of said first change gear drive, a second change gear drive for said pair of second feeding rollers, and said first change gear drive being operatively connected with said second change gear drive.
Claim 2
Dependent Claim
162 words
In a press having an upstanding stand, an apparatus for performing a timed, settable working material feed for said press, said press having a ram, and at least one drive means for said ram and said feed apparatus, said feed apparatus comprising a first pair of stepwise driven feeding rollers mounted on one side of said stand and a second pair of feeding rollers on the other side of said stand, intermediate drive means for said feed rollers, comprising a first change gear drive having a coarse-setting step to selectively set the amount of a basic feed and a correction or fine-setting step to selectively provide a fine adjustment of said basic feed, said step-by-step switching device operatively connected with said pair of said first feeding rollers by means of said first change gear drive, a second change gear drive for said pair of second feeding rollers, and said first change gear drive being operatively connected with said second change gear drive.
Claim 3
Dependent Claim
24 words
The apparatus, as set forth in claim 1, wherein said second change gear drive is disposed directly preceding said pair of second feeding rollers.
Claim 4
Dependent Claim
73 words
The apparatus, as set forth in claim 1, which includes a shaft rotatably mounted on said stand in horizontal position within a range above said rollers, for operative connection of said pairs of feeding rollers, a bevelled gear drive coordinated to and operatively connected with the respective ends of said shaft, a universal shaft, and a drive gear coordinated to the corresponding pair of said feeding rollers by means of said universal shaft.
Claim 5
Dependent Claim
65 words
The apparatus, as set forth in claim 1, Wherein said pair of said second feeding rollers include an upper roller mounted for moving to a given height, and a cam disc continuously driven by said apparatus and including means for adjusting its angular position and connected for adjusting said cam disc for lifting said upper roller independently from said pair of said first feeding rollers.
Claim 6
Dependent Claim
20 words
The apparatus as set forth in claim 1, wherein said second change gear drive comprises exclusively a second fine-setting step.
Claim 7
Dependent Claim
52 words
The apparatus, as set forth in claim 1, wherein said step-by-step switching device is connected with said coarse setting step by means of said first change gear drive, and said coarse setting step is operatively connected with said pair of said first feeding rollers by means of said correction or fine-setting step.
Claim 8
Dependent Claim
29 words
The apparatus, as set forth in claim 6, wherein said second change gear drive is operatively connected from said correction or fine-setting step of said first change gear drive.
