Abstract
Abstract A folding machine includes an entrance feed for the infeed of materials to be folded which are operated on by a plurality of folding devices arranged along the feed path, each of which feeds the material after folding into a receiving pocket which has an adjustable stop. The stop is adjusted so that the materials being fed are received in the pocket at the correct location so as to position them for subsequent folding or for ejecting at an ejection point. The invention provides a conveyor belt which operates so that an upper transport reach is movable below the ejection point to receive the folded materials. Associated with the conveyor is a brake element which overlies the materials which are fed on the conveyor transport reach. The brake element rests on the folding material and is mounted so that it applies a yieldable pressure on the materials as they moved therealong. A flexible member is connected between the brake element and the adjustable stop of the last folding pocket so that the position of the brake element can be adjusted relative to the ejection point by the same amount that the adjustable stop is adjusted in respect to its associated pocket.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
167 words
In a machine for folding a plurality of materials having means for feeding the materials to be folded in succession along a transport path, a plurality of folding devices arranged along the transport path including a folded material receiving pocket with an adjustable stop position to receive the materials at the location of the stop and for delivering the materials in the pocket to an ejection point, the improvement comprising a conveyor belt having a transport reach movable below the ejection point in a position to receive the folded materials, at least one brake element overlying said transport reach and resting on the folded materials moving thereon, mounting means associated with said brake element so that said brake element applies a yieldable pressure on the materials as they are moved, and a member connected to said mounting means and to the adjustable stop and being actuated by movement of the adjustable stop to move said mounting means by a corresponding amount in respect to said ejection point.
Claim 2
Dependent Claim
167 words
In a machine for folding a plurality of materials having means for feeding the materials to be folded in succession along a transport path, a plurality of folding devices arranged along the transport path including a folded material receiving pocket with an adjustable stop position to receive the materials at the location of the stop and for delivering the materials in the pocket to an ejection point, the improvement comprising a conveyor belt having a transport reach movable below the ejection point in a position to receive the folded materials, at least one brake element overlying said transport reach and resting on the folded materials moving thereon, mounting means associated with said brake element so that said brake element applies a yieldable pressure on the materials as they are moved, and a member connected to said mounting means and to the adjustable stop and being actuated by movement of the adjustable stop to move said mounting means by a corresponding amount in respect to said ejection point.
Claim 3
Dependent Claim
97 words
In a folding machine according to claim 1, wherein said member comprises a flexible member extending between said stop and said mounting means for said brake element, said folded material receiving pocket being located on one side of said ejection point and said conveyor belt transport reach being located on the opposite side of said ejection point means guiding said member between said stop on the folded material receiving pocket in said mounting means so that said mounting means is moved in an opposite direction in respect to the ejection point from the movement of the stop.
Claim 4
Dependent Claim
69 words
In a machine according to claim 1, wherein said mounting means comprises a plate over which said transport reach is movable, a support rod member extend along said conveyor, a support member engaged over said support rod member and being movable backwardly and forwardly therealong, said support member carrying an upright bracket on each end rotatably supporting a shaft, said brake element comprising a disc carried by said shaft.
Claim 5
Dependent Claim
58 words
In a folding machine according to claim 3 wherein said upright supports for said shaft includes an upwardly opening recess into which said shaft is positioned, said brake elements comprising rollers on said shaft, said shaft being supported with said rollers for upward and downward movement in accordance with the weight thereof bearing against the material being fed.
Claim 6
Dependent Claim
69 words
In a folding machine according to claim 1, wherein said brake element mounting means includes a flat plate disposed below said transport reach on which said transport reach is guided in an upstanding support plate at each side of said flat plate defining a receiving bearing, said brake elements comprising a shaft engaged in said receiving bearing carrying a roller engaged on the materials fed over said transport reach.
Claim 7
Dependent Claim
42 words
In a folding machine according to claim 1, wherein said mounting means comprises a holder mounted alongside said conveyor having a flat part disposed directly below said transport reach, and a guide rail on each side of said holder supporting said holder.
Claim 8
Dependent Claim
35 words
In a folding machine according to claim 1, wherein said member comprises a flexible member, an idler pulley arranged between said mounting means and said adjustable stop, said flexible member being guided around said pulley.
Claim 9
Dependent Claim
72 words
In a folding machine according to claim 1, wherein there are two separate laterally spaced conveyors, said brake elements comprising two laterally spaced cylindrical discs engaged over the transport reaches of each of said conveyors and a holder comprising said mounting means including upright support elements on each end having open top bearings, a shaft carrying said disc engaged in said open top bearings, said disc having peripheries with a friction coating.
Claim 10
Dependent Claim
58 words
In a folding machine according to claim 8, wherein said discs having a hub portion with bores, annular slot defined in each of said bores between the ends thereof, a friction element engaged on the periphery of said disc and riding in said slot forming a friction clutch for each of said discs providing a frictional clutch engagement.
Claim 11
Dependent Claim
41 words
In a folding machine according to claim 1, wherein said mounting means comprises an upright support member alongside said conveyor, said brake element including a resilient member carried by said support means bearing against the materials carried by said transport reach.
Claim 12
Dependent Claim
28 words
In a folding machine according to claim 10, wherein said resilient member includes a ball supported over said transport reach and rotatably engaging the materials on said reach.
