ABSTRACT:
A feed mechanism for a folding machine and a folding machine for sheet material. The folding machine has a plurality of rollers for folding sheet material, drive means for rotating said rollers, at least two pocket assemblies with microswitches positioned to be contacted by sheet material passing through said pocket assemblies. The drive means are controlled by these pocket assembly microswitches and a cam microswitch, which is contacted by a cam attached at one end of a roller.
The feed mechanism consists of a roller flat having a curved side and a flat side. Between the flat side and a second roller, a gap is formed allowing sheet material to be inserted directly into a first pocket assembly. The sheet material thus inserted contacts a microswitch located in the pocket assembly activating the drive means which turns the roller flat so that its curved side forms a take-in nip with the second roller, feeding the paper in further to begin the folding process.
