Abstract: 1,081,038. Feeding webs. FADUM TEKNISKE A.S. Nov. 15, 1965 [Nov. 16, 1964], No. 48440/65. Heading B6B. [Also in Division F2] A roller for transversely registering a moving web has a larger diameter at its centre 2 than at its ends and has rings 14 of a material having a higher coefficient of friction than the remainder of the roller at its ends. The roller is rotatably mounted with bearings 11 on a tube 10 which is centrally pivoted at 8 to a shaft 6. The rings 14, of for example rubber, are positioned in recesses (12, Fig. 3) by metal spacing rings 13. The longitudinal positioning of each ring 14 with respect to the roller (which is determined by the width of web and whether it is necessary to have the edge of the web running partly over the ring 14 or not) can be determined by the width and number of the spacing rings 13. If the web moves out of register, and moves fully on to a ring 14 at one end of the roller, the roller swivels about the axis 8. The increase in force due to friction at the web edge promotes this swivelling action which restores the register of the web.
