Abstract (en)
[origin: CA2041171A1] The invention concerns a process for regulating the parallelism of the two beams (5, 6) of a cutting press designed for converting sheet or weblike matter into package. The press comprises a frame made of a lower crossbar (1) and an upper crossbar (3) connected to one another by means of lateral posts (2). An upper beam (5) is fitted on the upper crossbar (3). A lower movable beam (6) is raised and lowered with each operating cycle by means of a drive system (20a, 20b) supported by the lower crossbar (1) by means of bearings (33a, 33b). The bearings (33a, 33b) can be shifted vertically when the drive system (20a, 20b) is situated in lower dead center position in such a way as to regulate the parallelism of the lower beam (6) with regard to the upper beam (5). When the press accomplishes its operating cycle, a deviation of parallelism (e) is measured when the drive system (20a, 20b) is situated in upper dead center position. When the said lower dead center is reached, the bearings (33a, 33b) are shifted vertically so as to have the lower beam (6) tilt in the direction contrary to the tilt resulting from the deviation of parallelism (e) measured in the said upper dead center position.
