Abstract: A dispenser for tinfoil and other sheet materials, wound on a roll, comprises a cylindrical roll-supporting mandrel fixedly secured to one of two flat cheeks and provided at its free end with a threaded extension of reduced diameter passing through a hole in the other cheek. The other cheek is held by a milled knob, threaded onto the outwardly projecting end of the mandrel extension, in contact with a tubular spacer of the same diameter as the mandrel, traversed by that extension, or with a disk-shaped counternut threaded onto that extension between the two cheeks whereby the effective length of the mandrel is adjustable to accommodate rolls of different sizes. A serrated blade paralleling the mandrel has one end fixed to the first sheet and traverses with its opposite end a slot in the other cheek.
