Patent attributes
An unpowered, manually operable apparatus (10) for dispensing cushioning wrap material (13) includes a frame (12), a roll (14) of interleaf material (16) rotatably secured to the frame, a roll (18) of expandable sheet material (20) in an unexpanded form rotatably secured to the frame adjacent the roll of interleaf material, and a tensioning assembly (60, 70, 80, 90) operably associated with the roll of expandable sheet material to control rotational resistance thereof. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is pulled with the interleaf material by a user. Typically, the roll of interleaf material and the roll of expandable sheet material are secured to the frame such that respective longitudinal centerlines of each roll are substantially aligned. In addition, typically, the axial directions of the rolls are substantially parallel.
