ABSTRACT:
A method and apparatus for feeding sheets, particularly fabrics, from a stack comprises an arrangement for: engaging the opposite edges of the upper sheet of the stack by a pair of restrainer members, bringing a pick-up head into engagement with the upper sheet of the stack while producing air streams from the pick-up head directed outwardly across the opposite edges of the upper sheet of the stack, lowering the pick-up head to depress the stack below the restrainer members whereby the air streams cause the opposite edges of the upper sheet of the stack to curl upwardly to clear the restrainer members, lifting the upper sheet from the stack, and permitting the stack to rise so as to bring the next sheet into engagement with the restrainer members.
