Abstract

A folding machine for folding sheet material comprises a housing defining a space and having an in-take opening and a discharge opening for sheet material before and after it is folded. A frame is provided in the housing and carries four rollers which are engaged with each other to form a take-in nip for receiving sheet material from the in-take opening, a first folding nip for executing a first fold on the paper and a second folding nip for executing a second fold of the paper. The rollers are engaged to each other by gears and are rotated by a single electric motor for moving the sheet material from the take-in nip to the first folding nip and from the first folding nip to the second folding nip. A pocket is formed upstream of the first folding nip in the housing for receiving the sheet of paper to stop its forward progress. The sheet of paper is continued to be fed by the take-in nip so that it folds into the first folding nip which draws the now once folded paper from the first pocket. A second pocket is provided downstream of the first folding nip to permit the second folding nip to form a second fold whereupon the folded sheet material is discharged through the discharge open…
