Supply device for a machine for transversely cutting at least one strip of flexible material

摘要

A supply device (10) for a machine for transversely cutting two strips (11 and 12) of a flexible material, in particular a strip of paper, moving continuously, to produce separate stacks of documents cut transversely according to predetermined formats. The device comprises lower and upper driving mechanisms (13, 14) associated with the two strips (11, 12) of flexible material respectively, which each include a mechanically rotated first roller (13a, 14a) and a freely rotatable second bearing roller (13b and 14b). The driving mechanism is mounted on a frame (15) supported by a movable platform (16) which is rigidly connected to a linear actuator (17) arranged to be moved transversely with respect to the direction of movement of the strips (11 and 12). Optical reading cells (11a, 11b, 12a, 12b) define the operating modes of the driving servomotors (13b and 14b) and of the linear actuator (17).

主权项

1. A supply device (10) for a machine (20) for transversely cutting at least one strip of flexible material (11, 12) moving continuously, to produce separate stacks of documents cut transversely according to determined formats and for shifting the stacks of documents laterally with respect to one another in order to identify the stacks of documents,
the device comprising at least one driving means (13, 14) associated with the strip of flexible material including at least one driving roller (13a, 14a) which is mechanically rotated and a bearing roller (13c, 14c) which is freely rotatable around an axis, the device comprising at least one linear actuator (17) arranged to support the driving means (13, 14) of the strip of flexible material (11, 12) to be cut, and to shift laterally and selectively the strip of flexible material upstream of the transverse cutting machine (20) in order to form distinct document stacks, and the device comprises detection means associated with each of the continuously moving flexible material strips (11, 12), each of the detection means including at least one cell (11a, 11b, 12a, 12b) for reading at least one code containing information relating to at least one of a cutting format and a lateral positioning of the documents cut.
