Abstract (en)
[origin: EP0365470A2] The device for attaching the trailing end of a web (2) to the leading end of another web (18) in a packaging machine has a first servo device (15) with a motor (31) for driving the web (2) running off roll (1) and a second servo device (16) with a motor (41) for backup driving of the web (2), a buffering device (22) compensating the differences in speed which the web (2) may exhibit before or after it, seen in the direction of flow. The second servo device (16) is controlled by a control signal Vas, which is supplied by a computer, in order to effect a reduction of the web speed to zero at a given moment, and thereby facilitate the attaching of the two web ends. <IMAGE>
