Abstract
Abstract A device for cutting plate material, comprising a supporting face for the material constituted by a flexible belt guided about rollers which are supported by a carriage movable along a frame, together with a transverse slit, and the cutter, the flexible belt being supported by an articulated supporting table, which is constructed from a plurality of juxtaposed oblong plates the long sides of which are hingedly interconnected, while their ends bear on supporting members provided on the two longitudinal edges of the frame and movable into and out of the plane of the articulated supporting table, under the action of cams provided on the carriage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
350 words
A device for cutting plate material, comprising a supporting face for the material to be cut that is constituted by a flexible belt which is guided about two guide rollers which are mounted on either side of, and at a short distance from, a cutter, and also about at least one other guide roller placed thereunder, the said rollers being supported by a carriage which also carries the cutter and which is movable in a longitudinal direction along a frame, the arrangement being such that the transverse slit, determined by the edges of the belt and in which the cutter lies, moves with the movement of the carriage along the flexible belt, while the portion of the flexible belt which supports the material is supported by an articulated supporting table, disposed thereunder, the ends of which are fixedly secured to the two ends of the frame and which supporting table is constructed from a plurality of juxtaposed oblong supporting elements, coupled to each other, the ends of which are supported by the two longitudinal edges of the frame, while the carriage is provided with cams by means of which, when the carriage moves in the longitudinal direction of the belt, the support of the supporting elements before the carriage is eliminated, the said articulated supporting table being guided on guide members provided on either side of the guide rollers and rotatably supported by the table, the axis of rotation of the guide members being parallel to the axis of the guide rollers in such a way that the portion of the flexible belt passing over the guide rollers is enclosed by a portion of the articulated supporting table, characterized in that the supporting element comprises oblong plate the long sides of which are supporting interconnected, while the ends of these plates bear on supporting members provided on the two longitudinal edges of the frame and movable into and out of the plane of the articulated supporting table, said supporting members being capable of being moved out of the plane of the articulated supporting table by cams provided on the carriage.
Claim 2
Independent Claim
350 words
A device for cutting plate material, comprising a supporting face for the material to be cut that is constituted by a flexible belt which is guided about two guide rollers which are mounted on either side of, and at a short distance from, a cutter, and also about at least one other guide roller placed thereunder, the said rollers being supported by a carriage which also carries the cutter and which is movable in a longitudinal direction along a frame, the arrangement being such that the transverse slit, determined by the edges of the belt and in which the cutter lies, moves with the movement of the carriage along the flexible belt, while the portion of the flexible belt which supports the material is supported by an articulated supporting table, disposed thereunder, the ends of which are fixedly secured to the two ends of the frame and which supporting table is constructed from a plurality of juxtaposed oblong supporting elements, coupled to each other, the ends of which are supported by the two longitudinal edges of the frame, while the carriage is provided with cams by means of which, when the carriage moves in the longitudinal direction of the belt, the support of the supporting elements before the carriage is eliminated, the said articulated supporting table being guided on guide members provided on either side of the guide rollers and rotatably supported by the table, the axis of rotation of the guide members being parallel to the axis of the guide rollers in such a way that the portion of the flexible belt passing over the guide rollers is enclosed by a portion of the articulated supporting table, characterized in that the supporting element comprises oblong plate the long sides of which are supporting interconnected, while the ends of these plates bear on supporting members provided on the two longitudinal edges of the frame and movable into and out of the plane of the articulated supporting table, said supporting members being capable of being moved out of the plane of the articulated supporting table by cams provided on the carriage.
Claim 3
Dependent Claim
89 words
A device according to claim 1, characterized in that the supporting members comprises supporting fingers rotatable about a vertical axis and secured to the longitudinal beams of the frame, which fingers are kept under spring tension in a position essentially perpendicular to the longitudinal beams, while the carriage carries, in the vicinity of each cam and before the guide member, a supporting slide serving to support the articulated supporting table, the supporting surface of the slide being at a higher level than the upper surface of the supporting fingers.
Claim 4
Dependent Claim
37 words
A device according to claim 1, characterized in that the carriage carries, between the guide members for the articulated supporting table and the guide rolLers for the flexible belt, a supporting plate which supports the flexible belt.
Claim 5
Dependent Claim
50 words
A device according to claim 1, characterized in that a pressure belt is provided on either side of the cutting slit which is bearing with an adjustable pressure on the material and which is guided about two rollers, one of which is driven synchronously with the motion of the carriage.
