An apparatus (1) for dispensing a flexible web material comprises a closed cabinet (2) with dispensing opening (3) for the web, and supporting means (6, 9-14) mounted in the cabinet for rotatable support of two rolls (7, 8) of the web material, the web (15) of the first roll (7) being guided out of the cabinet (2) along a plurality of guide rollers (25, 28) and through the dispensing opening (3) and the leading end (17) of the web (16) of the second roll (8) lying ready in a reserve position within the cabinet (2), whereas means (18) are provided for feeding said leading end of the second web through the dispensing opening (3) out of the cabinet (2) by means of the remainder of the first web. Said means (18) include a pressure roller (10) and a supporting roller (20) which are mounted in the cabinet (2), the first web (15) and the leading end (17) of the second web (16) being led between the pressure roller (19) and the supporting roller (20). The pressure roller (19) is pivotable by means of the first web (15) between a working position in which the pressure roller (10) presses both webs (15,16) on the supporting roller (20) and a rest position in which the pressure roller (19) is spaced from the supporting roller (20) in such a manner that the pressure roller (19) is each time pivoted into the rest position when a piece of the first web (15) is delivered so that the leading end (17) of the second web (16) remains in the reserve position, whereas, as soon as the trailing end of the first web (15) leaves the first roll (7), the pressure roller (19) is retained in the working position and the leading end (17) of the second web (16) is fed out of the cabinet (2) through the dispensing opening (3) by drawing out the last piece of the first web (15). |
