Dispensing machine for wipe material with anti comeback material after traction device

摘要

Dispensing apparatus for drying materials precut comprising an enclosure (1) for receiving a module (M) supporting the material strip previously cut to be unwound and distribution mechanisms of said band, and cover (2) hinged and articulated relative to the housing, said module (M) comprising lateral flanges (3) between which is arranged a coil (B) of material and a guiding device (4) of said strip forms a positionally controlled by cocking levers (5) disposed on either side of said side flanges (3) of the module rocker, the module comprising a spoiler (6) mounted transversely between said flanges (3) and a support plate (7 ) between which the strip of material to be removed by the user, to be in contact with said material web to ensure its advance characterized by comprising a device (D1) anti comeback band material comprising a shaft (8) of great length arranged parallel to and above the rear face of said flap (6), said shaft having in its middle portion a roller (9) opposite a central opening (6.1) arranged on the wing ( 6), said shaft at a first end (8.1) attached to a block (10) arranged to subsequently receive a free wheel ratchet for rotation of the shaft (8) in one direction and at its other end (8.2) a shaped lever connecting rod (11) articulated on a shaft of a fixed part (6.2) of the flap (6) to meet an elastic return means (13) and said axle (8) is fixed on one side and It has a capacity for elastic separation relative to the spoiler (6) to meet said recoil means (13) and displacement of the lever (11) defining the limit position of the roller (9) relative to the spoiler (6) in overflow or relative to the plane of said flap, and that the setting wheel free inside the block (10) produces a blockage in comeback of the material web by the effect of locking in position of the roller (9).
