DELIVERY MECHANISM IN A ROLL REWINDER

摘要

Roll rewinder delivery mechanism, the roll rewinder being configured to wind a roll of sheet material from a bulk roll, the roll rewinder comprising a roll mandrel and a transfer mechanism; wherein the delivery mechanism includes a reciprocating carrier associated with the moll mandrel, an outward movement of which unloads said roll mandrel from said transfer mechanism, and an inward movement of which loads the roll mandrel towards said transfer mechanism; wherein the reciprocating carrier interacts with the transfer mechanism such that, during an unloading action of the delivery mechanism the reciprocating carrier causes elements of the transfer mechanism to move in a direction away from the roll mandrel at its winding position whereas during a loading action of the delivery mechanism, the reciprocating carrier causes elements of the transfer mechanism to move in a direction towards said roll mandrel at its winding position. The rewinder may comprise a user-actuated manual drive mechanism and may permit users to generate a roll having a selected quantity of sheet material. The roll rewinder may be self-threading and may be capable of operating with no external power source. The transfer mechanism may in particular comprise elements of a threading mechanism.
