Material, such as fabric, is unwound from a bolt (7) in a magazine (6) and deposited on a table (1). The magazine (6) comprises a chain (8) having suspension elements (11, FIG. 2) for receiving spindles (10) of the bolts (7). The required bolt (7) is locked in an unwinding position and held firmly, but rotatably, by supporting means (14) and retaining means (18), all in the form of ball bearings. The bolt (7) is rotated by a drive element in the form of a friction wheel or a conveyor belt which drivingly engages either the periphery of the bolt (7) or the spindle (10). In FIG. 2, the drive element comprises a friction wheel (24) which is biased by a spring (25) into driving engagement with a further friction wheel (19) mounted on the spindle (10). The apparatus enables the web to be deposited on the table free of tension.
