Claims
- 1. A device for fabricating cut, disjoined and doubly-folded paper products from rolls of continuous paper sheeting comprising:
- paper side entry sheeting feed means;
- rotary cutting rolls;
- paper shearing and folding assemblies;
- product transport means;
- product ejection means, and
- motive means,
- in which said device includes a drive roll that supplies said assemblies from said side entry feed means with paper sheeting, said side entry feed means folding said sheeting and said rotary cutting rolls cutting the shape of said products in said folded sheeting, said assemblies shearing and again folding said folded and cut sheeting into individual doubly folded products,
- wherein said side entry paper sheeting feed means comprises a folding guide over which said sheeting passes and two folding rolls positioned substantially at right angles to said guide through which said sheeting feeds, said sheeting being thereby transversely received folded in half, and longitudinally delivered
- wherein said motive means drives and coordinately interconnects with said rotary cutting rolls, paper shearing and folding assemblies, product transport means, and product ejection means,
- wherein, said product transport means collects said doubly folded products and moves them in collated sheaves to said product ejection means said product ejection means ejecting said sheaves from said device, and
- wherein further, at least two of said assemblies are mounted one over the other in a vertical array, and at least two of said side entry paper sheeting feed means are located adjacent each other, said sheeting from said sheeting feed means being combined to form superimposed bands of folded sheeting, the bands of folded sheeting then being fed to said rotary cutting rolls, to said paper, shearing and folding assemblies, and to said product transport means, said transport means collating said doubly-folded products into sheaves of product that are ejected from said device by said product ejection means.
- 2. A device according to claim 1 in which said guide is substantially triangularly shaped and said folding rolls are inscribed with helical threads having a pitch that widens as the threads proceed outwardly from the center of said rollers, the threads providing a force acting outwardly from said center on said sheeting in contact therewith, thereby smoothing said folded sheeting.
- 3. A device according to claim 1 wherein said paper products are toilet seat covers, wherein said rotary cutting rolls cut seat cover holes in said sheeting and seat cover corners in the edges thereof, and wherein further, said shearing and folding assemblies shear the sheeting into disjoined seat covers and folds said seat covers into doubly folded covers.
- 4. A device according to claim 1 wherein said product ejection means includes cam-activated product ram means, said ram means being operated by said coordinately interconnected motive means so that when said sheaves are transported to a point adjacent said product ejection means by said product transport means, said sheaves are ejected from said device by said ram means, and wherein said product ejection means is transversely adjustable to permit the positioning of said ram means adjacent to said transported sheaves.
- 5. A device for fabricating cut, disjoined and doubly folded paper products from rolls of continuous paper sheeting including:
- at least one side entry paper sheeting feed means, comprising a triangularly shaped folding guide over which said sheeting passes, and two folding rolls positioned at right angles to said folding guide, said sheeting being thereby singly folded, transversely received and longitudinally delivered;
- rotary cutting rolls that cut seat cover holes and seat cover corners in said singly folded sheeting;
- at least one paper shearing and folding assembly, said assembly including a drive roll, for feeding to said assembly said singly folded and rotary cut sheeting, said assembly shearing and again folding said sheeting into individual doubly folded toilet seat covers;
- product transport means that collects said individual doubly folded toilet seat covers and moves them in collated sheaves of product;
- product ejection means that receives said product sheaves from said product transport means and ejects them from said device; and
- motive means for driving and coordinately interconnecting with said rotary cutting rolls, drive roll, paper shearing and folding assemblies, product transport means and product ejection means.
