Abstract: A very compact play-free bearing unit includes a bearing that runs without play while having a reasonably large play when assembling and during disassembly of the bearing unit from its axle. The bearing unit uses three bearings, one of which is mobile, and thanks to a preloading mechanism the play is removed when loaded. Thanks to an amplification lever, the preloading unit is able to function either with a pneumatic actuator or with a hydraulic actuator.

Abstract: A unit for separating a pre-cut-out substrate into a plurality of separate sub-substrates (20). The unit includes upstream (2) and downstream (2a) transverse guides; conveyor ramps, which convey the pre-cut-out substrate and the separate sub-substrates (20), the ramps are slidably and pivotably mounted on the guides (4). Upstream and downstream locks holds each ramp (3) in a locked position. A movable element supports upstream and downstream unlocking devices for engaging the upstream and downstream locking devices to release the ramps (3). Upstream and downstream grasping devices grasp and drive the ramps (3) along the upstream (2) and downstream (2a) guides to arrange the ramps in a fan-like configuration.

Abstract: A device for stacking sheets delivered on a first conveyor in a plurality of parallel streams of overlapping sheets, includes a second conveyor moving slower than the first conveyor that compacts the streams as they exit the first conveyor; a third conveyor that receives the streams from the second conveyor; and a plurality of stackers, each aligned with one of the streams exiting the third conveyor, formed of endless belts positionable horizontally which cooperate with stop members to stack the incoming sheets. Completed stacks are then moved downstream on the belt. When sheets in a stream are determined to be defective; its belt for that stream is tilted, and the stream falls onto a fourth conveyor for disposal.

Abstract: Delivery and ejection device (20) for flat elements (2) into a machine working them, in particular into a machine (10) of packaging production continuously delivering a plurality of lines of flat elements (2) arranged into parallel streams (22) successively onto three conveyor belts (13, 23, 33). These streams are recurringly delivered into a stacker (40) thanks to a mechanism (60) of drive and interruption of the streams. The device (20) allows to separately reject at least one stream towards a reject conveyor belt (90) comprising flat elements (2) scanned as being defective. The mechanism (60) includes two carriages, one upper (61) and the other lower (62), able to move simultaneously, at the same speed and into opposite direction along a axis parallel to the streams lines (22).

Abstract: A rotating cutting apparatus has an arrangement for controlling and finishing the cutting which is arranged between a cutting station and a receiving station. This arrangement includes a conveying arrangement for box blanks, an arrangement for acting on the cut flaps of the box blanks to bend them out of the plane of the blank and an arrangement for pressing the flaps back into the plane of the blank.
