ABSTRACT:
The invention relates to a dispenser for a web of wrapping material having a conveniently operable manual braking mechanism. The invention generally comprises first and second side members adjacent to each side of a roll of wrapping material, respectively. Each of these side members has a bearing member disposed thereon for supporting the core of said roll and for permitting the core and roll to rotate incident to a dispensing operation. At least one of the bearing members is insertable into the core and has an expandible bearing surface on which the core end can rotate when the surface is in its unexpanded state. A manually operated means associated with one or both of the side plates operates to expand the bearing surface at the film is paid out, thereby acting as a braking means to apply tension to the film as it is applied.
