International Classification:

B41F 1324

US Classification:

101232, 198219, 198813, 198814, 198816

Abstract:

A belt drive for a machine for processing flat printing materials includes an endless belt revolving during operation, a roller about which the belt is partially looped, a frame with respect to which the roller is adjustable between a working position, wherein the roller keeps the belt tensioned, and a position moved away from the working position, wherein the belt is untensioned, and a spring device for biasing the roller into the working position thereof. Also included are a double crank by which the roller is articulated with the frame, and a stop which, due to a change in position of the double crank from a position corresponding to the working position of the roller into a position corresponding to the moved-away position of the roller, is carried out to a given extent beyond a dead-center position of the double crank, prevents a change in position beyond the given extent; and a machine for processing flat printing materials, which includes the belt drive.

US Classification:

101242, 101239, 101241, 271183

Abstract:

The delivery for a sheet-processing machine, such as a sheet-fed rotary printing press, has several braking devices which are movable transverse to a sheet transport direction. The delivery also has a sheet guiding elements that respectively cover the interspaces between adjacent braking devices at a level of the top edges. The sheet guiding devices are formed from a flexible tape material. The length of the tape transverse to the direction of sheet transport and seen from above is adjustable to the spacing between the adjacent braking devices.

US Classification:

271183, 271231

Abstract:

A sheet-braking system and method of operation for a delivery of a sheet-processing machine, includes a braking belt revolving during operation and undergoing periodic decelerating and accelerating phases. The braking belt further includes a braking strand passable over a suction region providing a suction effect passing through the braking strand. The suction region is overlapped throughout the duration of a respective decelerating phase, by a respective sheet deposited on the braking strand.

US Classification:

271207

Abstract:

A hurdle board assembly for separating sheet piles in a delivery of a sheet-fed printing machine includes a hurdle board. A plurality of spacer elements are connected to the hurdle board at locations in the vicinity of the border of one surface of the hurdle board. The spacer elements are respectively movable between a condition wherein they are retracted into the hurdle board and a condition wherein they extend vertically from the hurdle board. Respective prestressing devices are provided for prestressing the spacer elements, respectively, in a direction in the condition wherein the spacer elements, respectively, extend from the hurdle board. Respective locking devices are provided for securing the spacer elements, respectively, in the retracted condition. The locking devices are deactivatable from a side of the hurdle board so as to release the spacer elements.
