Abstract
Abstract An assembly for use in a machine for processing sheet or similar material comprising a rotatable tool and an opposing part between which the sheet material is fed and each mounted on a respective block and positionally adjustable relative thereto to vary the spacing between the tool and its opposing part, each block being movable in a direction transversely of the feed direction, and means for driving the tool and its opposing part each comprising a pinion supported on the block and meshing with a toothed shaft extending transversely of the direction of sheet material feed, wherein the toothed shafts are positioned so as to operate as feed rollers for feeding sheet material to the tool and its opposing part.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
An assembly for use in a machine for processing sheet or similar material, comprising: a rotatable tool; an associated opposing part between which and said rotatable tool sheet material is fed; a block in respect of each of said tool and said opposing part; means for mounting said tool and said opposing part on the said respective block for adjustment in a direction to vary the spacing between said tool and said opposing part; means for mounting said blocks for movement transversely to the direction of sheet material feed; drive means in respect of each of said tool and said opposing part and each comprising a pinion mounted on the said respective block and a toothed shaft extending transversely of the direction of sheet material feed and with which said pinion meshes; wherein said toothed shafts are so positioned and arranged as to operate as feed rollers for feeding sheet material to said tool and said opposing part.
Claim 2
Dependent Claim
158 words
An assembly for use in a machine for processing sheet or similar material, comprising: a rotatable tool; an associated opposing part between which and said rotatable tool sheet material is fed; a block in respect of each of said tool and said opposing part; means for mounting said tool and said opposing part on the said respective block for adjustment in a direction to vary the spacing between said tool and said opposing part; means for mounting said blocks for movement transversely to the direction of sheet material feed; drive means in respect of each of said tool and said opposing part and each comprising a pinion mounted on the said respective block and a toothed shaft extending transversely of the direction of sheet material feed and with which said pinion meshes; wherein said toothed shafts are so positioned and arranged as to operate as feed rollers for feeding sheet material to said tool and said opposing part.
Claim 3
Dependent Claim
27 words
An assembly as claimed in claim 1, wherein the periphery of said opposing part is toothed and meshes with said pinion of said opposing part drive means.
Claim 4
Dependent Claim
