Abstract
Abstract A stitching machine for stitching a folded stack of sheets along a fold line by a stitching head cooperating with a clinching anvil, has two conveyors located on opposite sides of the clinching anvil for transporting and carrying the angularly spread stack portions, while the inside of the fold line slides on the clinching anvil whose position is adjusted to the thickness of the stack. Manual means are provided for raising and lowering the conveyors with the stacks also in accordance with the thickness of the transported stacks and with the adjusted position of the clinching anvil.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
Stitching machine for a stack of sheets, comprising transporting carrier means for transporting a stack of sheets along a path; stitching means including at least one stitching head and a clinching anvil respectively located above and below said path; first adjusting means for adjusting the position of said clinching anvil toward and away from said stitching head for varying the distance between said clinching anvil and said stitching head in accordance with the thickness of said stack; and second adjusting means for adjusting in accordance with the adjusted position of said clinching anvil and with the thickness of said stack, the position of at least the part of transporting carrier means which passes said stitching means.
Claim 2
Dependent Claim
116 words
Stitching machine for a stack of sheets, comprising transporting carrier means for transporting a stack of sheets along a path; stitching means including at least one stitching head and a clinching anvil respectively located above and below said path; first adjusting means for adjusting the position of said clinching anvil toward and away from said stitching head for varying the distance between said clinching anvil and said stitching head in accordance with the thickness of said stack; and second adjusting means for adjusting in accordance with the adjusted position of said clinching anvil and with the thickness of said stack, the position of at least the part of transporting carrier means which passes said stitching means.
Claim 3
Dependent Claim
43 words
Stitching machine as claimed in claim 1, wherein said transporting carrier means include two parallel endless conveyor means, each conveyor means having a plurality of carrier links supporting said stacks; and wherein said clinching anvil is located between said two endless conveyor means.
Claim 4
Dependent Claim
63 words
Stitching machine as claimed in claim 2, wherein said second adjusting means include support means for supporting said two conveyor means for movement along said path, and manual means connected with said support means for moving the same with at least the parts of said two conveyor means passing said stitching means up and down in accordance with the thickness of said stack.
Claim 5
Dependent Claim
117 words
A stitching machine as claimed in claim 3, wherein said endless conveyor means have upper and lower runs each having carrier links, the carrier links of said upper run supporting said stacks; wherein said clinching anvil is located between said upper runs; and wherein said support means include two bar means supporting said upper runs of said conveyor means, respectively, said bar means having at least in the region of said stitching means two bar portions movable in vertical direction for raising and lowering said upper runs of said two conveyor means in accordance with the adjusted position of said clinching anvil and a linkage connected with said two bar portions and operated by said manual means.
Claim 6
Dependent Claim
85 words
Stitching machine as claimed in claim 4, wherein said linkage includes two vertical bars supporting said bar portions, two levers articulated to the lower ends of said vertical bars, and a shaft fixedly carrying said two levers; and wherein said manual means is operatively connected with one of said vertical bars for raising and lowering the same so that the other vertical bar is raised and lowered by said levers and shaft, and said two Bar portions are raised and lowered by said vertical bars.
Claim 7
Dependent Claim
58 words
Stitching machine as claimed in claim 1, wherein said transporting carrier means include two transporting carriers located on opposite sides of said clinching anvil; wherein said first adjusting means include a vertical plate located between said two transporting carriers and supporting said clinching anvil, and manually operated means for raising and lowering said plate with said clinching anvil.
Claim 8
Dependent Claim
68 words
Stitching machine as claimed in claim 1, wherein said transporting carrier means include two transporting carriers located on opposite sides of said clinching anvil, and supporting said stack; and wherein said second adjusting means include linkage means for simultaneously raising and lowering both said transporting carriers with said stack to a level corresponding to the level of said clinching anvil, and manual means for actuating said linkage means.
Claim 9
Dependent Claim
108 words
Stitching machine as claimed in claim 1, wherein said stack of sheets is folded along a fold line forming two angularly spread stack portions resting on said transporting carrier means and being engaged by the same so as to be transported along said path; wherein said clinching anvil is located under the transported stacks slidingly engaging the inside of said fold line; wherein said stitching head is located above said clinching anvil and the folded stacks thereon; wherein said first adjusting means adjust said clinching anvil in vertical direction; and wherein said second adjusting means adjust at least said part of said transporting carrier means in vertical direction.
Claim 10
Dependent Claim
66 words
Stitching machine as claimed in claim 8, wherein said transporting carrier means include two parallel conveyors located on opposite sides of said clinching anvil for supporting said two angularly spread stack portions; and wherein said second adjusting means include two support means for guiding said conveyors in a horizontal plane, and manual means for raising and lowering said support means with said conveyors and folded stacks.
Claim 11
Dependent Claim
90 words
Stitching machine for a stack of sheets, comprising transporting carrier means for carrying and transporting a stack of sheets along a substantially horizontal path; stitching means for stitching the transported stack and located in said path; and adjusting means for vertically adjusting at least the part of said transporting carrier means which passes said stitching means, relative to said stitching means and in accordance with the thickness of the stack so that the relative position of said stitching means and of said path corresponds to the thickness of said stack.
Claim 12
Dependent Claim
90 words
Stitching machine for a stack of sheets, comprising transporting carrier means for carrying and transporting a stack of sheets along a substantially horizontal path; stitching means for stitching the transported stack and located in said path; and adjusting means for vertically adjusting at least the part of said transporting carrier means which passes said stitching means, relative to said stitching means and in accordance with the thickness of the stack so that the relative position of said stitching means and of said path corresponds to the thickness of said stack.
