Embodiment Construction

[0025] This positioning method is shown in FIGS. 1 to 8 . The sheet 1 to be calibrated is conveyed by a sheet processing machine, such as a die-cutting press or the infeed table T of a printing press, in which it is necessary for the next operation to The sheet is precisely positioned to ensure that successive operations have the same reference position of the sheet, so that for example a printing or die-cutting operation does not deviate from a previous die-cutting or printing operation.

[0026]For this purpose, after the first operation, the infeed table T conveys the sheet 1 in the direction of the arrow F against a row of front end positioning means 2, the position of those front end positioning means 2 being adjustable. In this case, it is preferable to perform such an operation by means of at least one pinch roller 3 controlled by a cam or pneumatic cylinder (not shown), pressing the sheet 1 against the On a lateral sliding device 4 between the positioning devices 2. ...

Abstract

This device for positioning the sheets (1) comprises a feed table (T) owning means for driving the sheets, at least one front positioning stop (2) for stopping the leading edges of the sheets, register means for the lateral position of the sheets (1), means for comparing said position to a reference position , transverse drive means (7) of the sheets (1) and control means (6) for applying said drive means (7). The transverse drive means comprise a transverse slide (13) arranged between said stop (2) and said feed table (T), drive means (7) for said transverse slide (13) connected to said control means (6) and means (27 a, 27b) for jointly attaching the sheet (1) to the transverse slide (13).

Description

technical field [0001] The invention relates to a device for positioning sheets into an introduction station of a processing machine, comprising: an infeed table with drive means for said sheets; at least one stop for said sheets positioning front stop of the leading edge; means for recording the lateral position of said sheet; means for comparing said position with a reference position; means for driving said sheet transversely; and control means for controlling said drive means as a function of the direction and spacing between the recorded lateral position of said sheet and said reference position, and for moving said sheet when the sheet conforms to said reference position The latter stopped. Background technique [0002] In positioning devices, usually used for processing cardboard, solid board, corrugated board, such as converting presses, comprising multiple stations, the positioning of the sheets must be performed along the Vertical as well as horizontal are very a...
