An adjustment mechanism for an anvil roll has a body with first and second ends and a hollow interior. A bore extends from the first end into the hollow interior. The body is mountable to an axial end of the anvil roll at the first end. The hollow interior has first and second adjustment drives. The first adjustment drive extends from the second end of the body into the hollow interior and comprises a gear train with drive gears extending between a first adjustment operator and a first shaft extending from the body hollow interior through the bore of the body to the first end of the body. The second adjustment drive comprises a gear train with drive gears extending between a second adjustment operator and a second shaft extending from the hollow interior through the bore of the body to the first end of the body.

A tool-holder column for a unit for converting a flat substrate that has two upper bearings (14, 16) each for supporting one end of an upper rotary tool (10), and two lower bearings (15, 17) each for supporting one end of a lower rotary tool (11), the flat substrate being movable longitudinally between the upper rotary tool (10) and the lower rotary tool (11), the bearings (14, 15, 16, 17) being vertically movable in opposite directions on either side of the longitudinal direction (L) of movement of the flat substrate, and a common drive for the bearings (14, 15, 16, 17) allowing the bearings (14, 15, 16, 17) to be moved simultaneously by one and the same distance in opposite directions, and including a screw device (25), the bearings (14, 15, 16, 17) being mounted one above another on the screw device (25) such that the rotation of the screw device (25) causes the linear movement of the bearings (14, 15, 16, 17) in opposite directions.

A method for converting a flat substrate (W) in a station (3) for converting a flat substrate (W) that includes a rotary cutting unit (9) and at least one rotary deformation unit (7, 8) positioned upstream of the rotary cutting unit (9) in the direction of movement (L) of the flat substrate (W), the method including: determining the conversion parameters of the flat substrate (W), such as the deformation layout and cutting layout; choosing a sleeve (13) carrying a form for carrying out the deformation depending on the deformation layout; mounting the sleeve (13) on a mandrel (12) in the rotary deformation unit (7, 8); choosing the cutting tools (91, 92) depending on the cutting layout; mounting the cutting tools (91, 92) in the rotary cutting unit (9); and starting the conversion of the flat substrate (W).

A method for providing a nonlinear line of weakness on a web material including providing: a base, a support, a blade, and a driving means. The base may comprise at least one counter component having a length (L.sub.CC) where the counter component comprises a nonlinear shape having a shape width (W). The support may be operatively engaged with the base. The blade may have a length (L.sub.B) and may be disposed on the support so as to either contact or to come in close proximity with the counter component. At least one of the counter component and the blade may have a nonlinear shape and at least one of the counter component and the blade may comprise multiple segments.

The invention relates to a device for producing book cases, box lids or game boards with a cutting mechanism, which is arranged in the region of the blank feed and serves for cutting off the blank corners, wherein each tool pair of cutting cylinder and counterpressure cylinder is accommodated in a common bearing block and the bearing arrangement of the cutting cylinder has two mutually spaced eccentric bushes and a drive element arranged between the eccentric bushes.

The disclosed fiberglass cutting device with yoke-supported adjustable roller is a device, or “gun,” with on-the-fly—during operation adjustment of the spacing between the anvil roller and cutter. This adjustability is accomplished using only a single tension-adjusting knob located to one side of the anvil roller. This is superior to the prior art that required, at a minimum, two tension-adjusting knobs—one for each side of the anvil roller. To solve this problem, the fiberglass cutting device with yoke-supported adjustable roller supports the supports the anvil roller on both ends using a yoke. The position of the yoke is controlled by a single tension-adjustment knob that moves both arms of the yoke, thus maintaining the anvil roller in a position parallel to the cutting roller. The use of the yoke also avoids only supporting the anvil roller at a single end, which creates an unstable cantilevered-roller.

A cutting machine with a cutting support for material to be cut has a vertically movable, horizontal blade bar which bears a blade for cutting the cut material located thereon. A vertically movable, horizontal clamping bar is for pushing down the material to be cut. Two guide plates are arranged adjacent to one another, spaced apart in parallel in the same vertical plane, and in each case said guide plates have an inclined linear slot in which the blade bar is guided, and on the front faces thereof facing one another in each case have a vertical guide on which the clamping bar is guided.
