    摘要: A blind cutting machine includes a cutting blade; a base disposed on a first side of the cutting blade; and a guide disposed on a second side of the cutting blade. The first side is opposite the second side. The guide is adjacent to the cutting blade. The guide is configured to direct cutoff material to a waste collection area. An assembly includes a first member that is rotatable. A second member is configured to limit an amount of rotation of the first member. An actuator is configured to move the second member to a location wherein the second member does not limit the amount of rotation of the first member. The first member is configured to prevent a hand of an operator from coming into contact with the cutting blade.

    摘要: A cutting and dust or slurry collecting assembly that comprises: a) a circular saw blade (4) b) a blade guard (5) c) a cover device (6), and the cover device (6) has a front end (31), a rear end (32), a top surface (34), a bottom surface (36), elongated sidewalls (35), and a longitudinal passage (45,46) for the saw blade, d) the blade guard (5) and the cover device (6) being pivotally connected or connectable to one another via a hinge (40) in or adjacent to a lower rear corner of the blade guard (5), such that the cover device and the blade guard can be turned in relation to each other, e) a discharge member (52) is provided at the rear of said hinge and has an outlet (58) which can be connected to a vacuum source, f) a connection member (12) connects the discharge member (52) with at least one of the longitudinal passage (45, 46) and the cut created rear of the longitudinal passage, g) that the direction of rotation of the saw blade (4) is such that a circumferential part of the blade which has passed beyond the bottom surface of the cover device will move in a direction upwards-rearward towards the bottom surface In particular a rear arm distance (LR) between the hinge (40) and the rear end (32) is bigger than 0.2 R and preferably bigger than 0.25 R, thereby enabling a turning of the cover device (6) by pressing the rear end (32) towards the structure to be cut.

    摘要: A tool clamping assembly (38) for clamping a blanking tool (40) intended to be used in a blanking station of a sheet processing machine has a frame (46) to which the blanking tool (40) is to be clamped and at least one clamping element (48). The frame (46) has an aligning mechanism adapted for aligning the blanking tool (40) in a first direction. Further, the frame (40) has at least one support surface (60) oriented to support the blanking tool (40) in a second direction which is perpendicular to the first direction, and at least one abutment surface (62) oriented to support the blanking tool (40) in a third direction which is perpendicular to the first and second directions. The clamping element (48) is displaceable between an open position and a clamping position, the clamping element (48) being adapted for clamping the blanking tool (40) against both the support surface (60) and the abutment surface (62).
    Further, a blanking tool assembly with such a tool clamping assembly is shown.

    摘要: A sheet processing machine with a transfer mechanism for moving sheets along a handling direction of the sheet processing machine and with a waste evacuation device (36) for releasing the sheets. The transport mechanism comprises at least one sheet handling element (28) for moving a sheet. The waste evacuation device (36) further comprises a passage (46) formed between an opening surface (48) and a restraint surface (50). The at least one sheet handling element (28) comprises a first sliding element (68) and a second sliding element (70) being in contact with the opening surface (48) and the restraint surface (50), respectively, when passing the waste evacuation device (36).
