Abstract

1346418 Feeding webs FORMMASTER Ltd 16 June 1971 [19 June 1970] 29771/70 Heading B8R A web 11 is positively fed to a processing station 50 by means of a roller 101 having pin teeth 102 which co-operate with or form per. forations in the web. Downstream of the station 50 the web passes over a roller 106 which is operatively driven at a greater effective speed than the roller 101 and is in non-positive engagement with the web so that a predetermined tension is applied to the web as it leaves the processing station. As shown the station 50 is constituted by folding elements 51, 52 which are driven to operate in co-ordination with the feed roller 101, and the tension applied to the web can be varied, by adjustment of the pressure in the nip between roller 106 and a counterroller 107, to maintain longitudinal register of the web with respect to the folding operation. The web 11 is supplied from a reel 15 supported in bearing blocks 164 carried by lifting chains 160, the web being drawn from the roll by means of a roller 151 which is driven by a motor 152 controlled by magnetic proximity switches 155, 156 associated with a dancing roller 153 over which the web passes to form a storage loop, upstream of the feed roller 101.
