Abstract: In an apparatus for dispensing web sections from a roll the apportioning roll (1) is provided with a friction lining (2) and has a spiral guide (3) for actuating a thrust member (6). The thrust member (6) carries a knife (12) and is held in the spiral guide (3) by a return spring (15). A release anchor (10) is arranged for rotation on the thrust member (6) and includes stopper surfaces (17, 82) which may be in engagement with a stop (18) on the end surface (43) of the apportioning roller (1), providing a lock for preventing further rotation of said apportioning roll. When the paper web (39) is withdrawn across the apportioning roller (1), the apportioning roller (1) is rotated, the knife (12) is moved from its inoperative position into working position, the lock being actuated at the same time.

Abstract: In an apparatus for paying out web sections (50), comprising a dispenser roll (38) and a supply roll (40), a feeler (31) resting on the dispenser roll (38) determines the diameter thereof and, by way of levers, unlocks a detent (28) or a protrusion (78) disposed at a swinging plate (27) which carries the bearings (24). Hereby the swinging plate (27) is swung by a spring (48, 79) and thus the supply roll (40) resting on the bearing (24) is pressed against the paper web (39) withdrawn from the dispenser roll (38) and, together with it, against the toothed roller (21). Hereby the last rest of paper from the dispenser roll (28) is pulled off simultaneously with the leading end (41) of the web from the supply roll (40).

Abstract: The dispenser has a housing (42) which comprises a roll holder for the dispenser roll (39) and an outlet opening (55). A stationary knife (12) projects out of the outlet opening (55). An apportioning roller (1) is supported in the housing (42) in the path of the web of material (39) from the dispenser roll (38) to the outlet opening (55); it is adapted for stepwise rotation and to be arrested in a certain angular position by a control lever (15) so as to define a section length of the web of material (39). The knife (12) normally is covered by a cover strip (10) adapted to be moved away from the knife (12) by pulling at the web of material (39). The cover strip (10) is connected to the control lever (15) in such manner that the latter releases the apportioning roller (1) whenever the web of material (39) has been severed.
