Abstract: A dry-formed web is transferred at speeds in excess of 300 feet per minute onto a stable, porous, endless belt and both the dry-formed web and the belt are conveyed through the embossing nip. The combination of the dry-formed web and the belt are guided into the embossing nip so that the web and belt partially wraps the embossing roll before entering the embossing nip. As the embossing roll contacts the web, some of the air in the web is forced through the porous belt.

Abstract: The disclosure relates to an apparatus for dispensing sheet material such as paper towels. The dispensing apparatus when activated dispenses sheet material for a predetermined time which results in a predetermined length of sheet material being dispensed. The dispensing apparatus is actuated in response to the proximity of a portion of a hand of a user to the dispensing apparatus without the hand of a user contacting the apparatus. The dispensing apparatus dispenses sheet material from a roll of material by means of an electrical motor operating for a predetermined time to advance a predetermined length of the sheet material. The motor for advancing a predetermined length of the sheet material can be battery powered. The housing of the dispensing apparatus has a modular frame having a first compartment for the means for advancing the sheet material and a second compartment for the means for activating the advancing means.

Abstract: A dispenser for a roll (10) of sanitary paper wound on a hollow core (12). The dispsenser (10) has a core supporting member (16) that contacts the inner surface (13) of the core (12) and has a braking surface (20). The coefficient of friction between the member (16) supporting the roll (10) and the inner surface (13) of the core (12) is less than the coefficient of friction between the braking surface (20) and the inner surface (13) of the core (12). The dispenser (10) also includes a compliant member (18), such as a spring, connected to the core supporting member (16). The compliant member (18) is responsive to the weight of the roll (10) and urges the inner surface (13) of the core (12) toward the braking surface (20). At some point during the dispensing of the roll (10), the frictional force, or drag, developed between the inner surface (13) of the core (12) and the braking surface (20) increases as the weight of the roll (10) decreases.

Abstract: A rotary cutter or scissors for cutting a flexible web material as it travels around a rotating anvil roll. Mounted in the periphery of the anvil roll is an anvil blade having a cutting edge generally extending across the roll. Mounted in a fly knife roll rotating in synchronism with the anvil roll is a fly knife blade having a cutting edge that is also generally in axial alignment near the periphery of the fly knife roll. The axes of the anvil roll and the fly knife roll lie in the same plane and are spaced so that the locus of a cutting point on the fly knife blade intersects the locus of a corresponding cutting point on the anvil blade at two points, the first intersection point occurring as the cutting point on the fly knife blade is approaching the center of the anvil roll and the second intersection point occurring as the cutting point on the fly knife blade is traveling away from the center of the anvil roll.

Abstract: The method of autogenously bonding a nonwoven web formed predominantly of thermoplastic fibers is characterized by the steps of directing heat into the web from only one surface thereof to preheat the web, and then directing the preheated web through a bonding nip formed between opposed rolls, one of said rolls being hotter than the other roll, being capable of heating the web surface it engages to a temperature above the melt point of the thermoplastic fibers and being positioned to engage the surface of the web opposite the one into which heat was directed during the preheating operation; said webs being preheated by means completely independent of the opposed rolls that form the bonding nip, and most preferably by infrared panels. The nonwoven product formed in accordance with this method also forms a part of the instant invention.
