Abstract
A support for a moving web 6 comprises a hollow cylindrical sleeve 2 of resiliently flexible material, e.g. spring steel or plastics foil, carried by a roller 1 rollers 8 and 9 guide the web around the support as shown so that flutter or tension. variations in the web can be compensated-for by deformation of the sleeve 2. The roller 1 may be mounted for free or positive rotation or it may be fixed the sleeve 2 may be freely supported by the roller, or fixed to it when the roller is fixed, or can be positively rotated independently of the roller 1. The support may include further sleeves, positioned one inside another (Fig. 3, not shown), or may comprise a sleeve mounted on a pair of external rollers (Fig. 6, not shown). In winding or unwinding operations involving a web-roll the support can be arranged so that it guides the web to or from the roll, the sleeve being in contact with. the. outer winding of the roll (Figs. 5 and 6, not shown).
