ABSTRACT:
A system for folding limp material segments. A system includes a support surface for the segment, a belt assembly including a matrix of elongated parallel endless belts overlying that surface. A controller for permitting rotation of the surface with respect to the belt matrix, a fold-locus-defining assembly including a sheet member having a leading edge which may be adjustably positioned with respect to a material segment between the belts and the support surface, a sensor for generating a position signal representative of the segment on the support surface. A controller is responsive to the position signal and applied signals representative of a desired fold locus on the segment to control the belt assembly, the support surface, the fold-locus-defining assembly so that the segment is folded about a desired linear folding locus.
