Abstract
Apparatus is provided for manufacturing a wipe in a three dimensional form out of an essentially flat piece of material. The apparatus produces a blank (12) of essentially flat planar form with a pleat folded on each side. The folded blanks are fed by a conveyor belt (21) to an opening station (22). The opening station comprises a pair of movable pinch rollers (34, 35) which selectively grab individual blanks from the conveyor belt and feed them via belts (32, 33) to a pair of counter-rotating drums (30, 31). The blanks are ejected from the drums, which partially opens them up in the process. The partially open blanks are fed onto a shaped former (37), where the final process of forming the wipe into its chosen three dimensional form is completed.
