Abstract
Abstract A roll film dispenser having a base unit provided with a storage roll trough and an upwardly and forwardly located dispensing trough supports additional units to form a vertical array of staggered dispensing and storage troughs for rolls of perforated sheet film. Each unit is formed from a single piece of sheet material with angularly related converging portions forming the troughs. The forward walls of the dispensing troughs are at a sufficient angle with the vertical to eliminate the need for a core weight.
