Abstract: 747,246. Rollers. JOHNSON & JOHNSON. Aug. 16, 1954 [Sept. 10, 1953], No. 23814/54. Addition to 709,212. Class 42 (2). [Also in Group XVI] A strip-feeding roller comprises a hub member, a rim member encircling the hub member, elastic means around the hub member resiliently supporting the rim member, the elastic means having predetermined zones of varying strength arranged around the hub member, and locking means positively locking the rim and hub members against relative circumferential displacement, the locking means guiding the rim member for radial movement with respect to the hub member in direction substantially at right angles to the direction of strip feed. As shown, a strip 10, Fig. 1, having thick and thin sections is fed by rollers 11 and 12 carried by shafts 13 and 14. The shaft 13 carries a hub member 17 and a rim member 18, both preferably of steel; the rim member 18 may be faced with rubber or fabric. The hub and rim members are resiliently coupled by elastic means, such as a construction described in Specification 710,455, e.g. resilient tubes 20 of rubber. The tubes 20 are positioned in pockets 21 and 22 in the members 17 and 18. Thus, the tubes 20 resist radial movement of the member 18 with respect to the member 17. To permit the strip to be fed with even pressure the tubes 20 vary in strength by providing long and short tubes or thick and thin tubes arranged to correspond with the position of the thick and thin portions of the strip. Plates 23, Fig. 3, having radial keys 30 and 32, lock the members 17 and 18 together circumferentially by means of recesses 31 and 32 which are engaged by the keys 30 and 32 respectively. An annular clearance 25 between each of the plates 23 and extensions 26 of the member 17 permits radial movement of the member 18 with respect to the member 17 in a direction substantially at right-angles to that of the strip feed, the plates 23 also being movable with respect to the member 17 in a direction substantially at right-angles. to that of the strip feed when the roller 11 is rotated through 90 degrees from the Fig. 3 position.
