Packaging machines are often supplied with a web of packaging material of double width. During transport, the web of material (11) is sub-divided into two part webs (12,13) by means of a central longitudinal cut. The exact run of the web of material (11) and of the part webs (12,13) is monitored by
Packaging machines are often supplied with a web of packaging material of double width. During transport, the web of material (11) is sub-divided into two part webs (12,13) by means of a central longitudinal cut. The exact run of the web of material (11) and of the part webs (12,13) is monitored by edge-sensing members (21; 25,26). Any deviations from the correct position are transmitted as error signal to web-adjusting members (24; 27,28). These are each equipped with two deflecting rollers (32,33 or 59,60 or 62,63) arranged at a distance from one another and intended for deflecting the web of material (11) or part web (12,13). The two deflecting rollers are each adjusted in order to adjust the web run.

Apparatus for continuously separating a conveyed web of material into at least two part webs, in conjunction with a packaging machine, comprising: three web-adjusting member means (24, 27, 28) comprising three pairs of deflecting rollers (32, 33; 59, 60; 62, 63), respectively; the deflecting rollers
Apparatus for continuously separating a conveyed web of material into at least two part webs, in conjunction with a packaging machine, comprising: three web-adjusting member means (24, 27, 28) comprising three pairs of deflecting rollers (32, 33; 59, 60; 62, 63), respectively; the deflecting rollers of each pair being spaced from one another and being rotatably mounted on one of three adjustably pivotable common roller-carriers (34, 61, 64), one roller-carrier being for guiding the web (11), and two roller-carriers being for guiding said part webs (12, 13), respectively; web-monitoring members for controlling the positions of the three roller-carriers (34, 61, 64); wherein the two pairs of deflecting rollers (59 and 60 or 62 and 63) mounted respectively on said two roller-carriers (61, 64) are mounted in such a relative position in relation to one another that the two leading deflecting rollers (60 and 63) of said two pairs of deflecting rollers are arranged at a short distance from one another, while the trailing deflecting rollers (59, 62) of said two pairs of deflecting rollers are arranged at a longer distance from one another; and wherein said two roller-carriers (61, 64) are arranged on a common supporting frame (69) and are respectively adjustable by means of separate regulating gears in the form of servo-motors (80, 81) and spindle rods (82, 83).
