Abstract: A drive device for a load (18a) comprises a device for detecting accidental collisions with a motor (14a), a first, respectively a second position sensor (15a, 16a) disposed upstream, respectively downstream of a transmission assembly (12a) providing first and second values of position. A calculation unit (20) makes it possible to calculate an error signal (d) corresponding to the difference of these position values. Ways to discriminate are devised so as to analyze the successive error signals as a function of the path (xR) traversed by the load in a spatial reference frame (xR, d). Filters with rectangular spatial window or with exponential spatial window are particularly adapted for discriminating between errors due to an accidental collision and those due to other causes attributable to normal operation. One thus obtains particularly reliable and sensitive collision detection with a very low detection threshold.

Abstract: A method and device allows dynamic mask welding with online position adjustment in the high-speed welding of structured and endless plastic films. By a transparent driven mask roller provided with masks being arranged in a passive pressure roller surrounding the mask roller, detection can take place optically, and the mask roller and consequently the mask are synchronized with the film speed. Adjustment is detached from a film transport mechanism and does not influence the welding process and in this case, above all, the speed. High film transport speeds in the range of up to 1000 mm per second can be employed.
