摘要： A holder for flexible sheet material providing a substantially horizontally oriented housing containing convergent parallel walls forming an interior passageway with an opening. Contained within the housings' passageway are several spaced cylindrical rods with removable handles attached and exposed through the opening of the housing. The relationship between the diameter of the rods and the opening between the convergent walls is such that the rods can not pass through the opening and exit the housing. Sheet material moved into the opening in an upward direction between the inside front of the housing and the rods is secured by pulling on the handles attached to the rods to activate the wedging action. The sheet material can be removed from the holder by moving the handles vertically within the passageway to allow the sheet material to slip freely out of the housing. The maneuverability of these wedging rods via the affixed handles permits it to be used to secure sheet materials of various thickness, weights and textures.
