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

A supply device (10) for a machine (20) for transversely cutting at least one strip of continuously moving flexible paper (11, 12) to produce separate distinct stacks of documents, the at least one strip of flexible paper being cut transversely according to determined formats and for shifting the distinct stacks of documents laterally with respect to one another in order to identify the distinct stacks of documents,

• the device comprising at least one driving mechanism (13, 14) associated with the at least one strip of flexible paper and including at least one drive 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) which supports the at least one driving mechanism (13, 14) of the at least one strip of flexible paper (11, 12) to be cut, and which laterally and selectively shifts the at least one strip of flexible paper upstream of the transverse cutting machine (20) in order to form the distinct stacks of documents, and
• the device comprising 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.

A supply device (10) for a machine (20) for transversely cutting at least a strip of a 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 a driving means (13, 14) associated with the strip of flexible material including at least a drive 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 a linear actuator (17) arranged to support the driving means (13, 14) of the flexible material strip (11, 12) to be cut, and to shift laterally and selectively the flexible material strip upstream of the transverse cutting machine (20) in order to form distinct document stacks;
• wherein the driving means (13, 14) is mounted on a frame (15) supported by a movable platform (16) rigidly connected to the linear actuator (17) and arranged so as to be moved transversely with respect to a direction of movement of the flexible material strip (11 or 12);
• and
• at least two driving means associated respectively with at least two flexible material strips (11 and 12), and the two driving means are arranged over one another on the frame (15) supported by the movable platform (16) rigidly connected to the linear actuator (17), and arranged so as to move simultaneously the flexible material strips (11 and 12) transversely with respect to their direction of movement.
