A guide film supply mechanism feeds a guide film toward a winding mechanism. The guide film is a film in which a pair of supports, which is long in the longitudinal direction of a base film and is thicker than a product film, is disposed on both side portions of the upper surface of the base film that is formed to have a width larger than the width of the product film. A product film supply mechanism feeds the product film toward the upper surface of the guide film. The winding mechanism forms a film roll by winding the product film for each guide film. The tension of the product film is set to be smaller than the tension of the guide film.

A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

A retractable leash with integrated pooper scooper and bag management system, which provides a leash retractor, pooper scooper and bag dispenser that can be used to pickup bio-waste while walking domesticated pets, and method therefor. Components of the invention are the leash body shells, leash line, leash line hold button, pooper scooper scoops, scoop lever, scoop lever lock button, bag roll and bag clips, which, generally speaking, are configured as follows: the pooper scooper is connected to the bottom of the leash body shells, the scoop lever is located at the top of leash body with a lock button, the leash line is controlled by the leash line hold button located at the top of the invention, bag roll is located within the leash body shells and dispensed from either side of the invention. Bag clips are connected on both sides of invention to secure bag ends. The invention is used to leash and control pet distance from the pet owner during walks. In addition, the invention allows the owner to pick up and secure pet bio-waste, without the pet owner physically feeling the waste with their hands, at any time before, during or after the walk. Furthermore, the invention includes a reloadable bag dispenser system with door to install and secure bag roll within the device body.

A core for winding sheet material is proved. The core comprises a cylindrical tube having a longitudinally oriented slot formed therein, and a strip of soft material located in the slot. Because of the geometry of the slot and the strip, the strip may be softer in the central region but firmer where the core transitions from the relatively soft strip to the relatively hard tube. The leading edge of the sheet material imbeds itself into the soft central region of the strip as additional layers are wound around the core.

A apparatus for processing sheets includes: a conveyance unit conveying a sheet; a processing unit provided with processing members processing the sheet along a conveyance direction, and a moving unit moving the processing members in a width direction; and a controller. When a processing position in the width direction to be processed by the processing members is different between a sheet conveyed ahead by the conveyance unit and a subsequent sheet, the controller processes the subsequent sheet by using a processing member having a minimum movement distance from the processing position of the sheet conveyed ahead among the processing members.

A core for winding sheet material is proved. The core comprises a cylindrical tube having a longitudinally oriented slot formed therein, and a strip of soft material located in the slot. Because of the geometry of the slot and the strip, the strip may be softer (less compressed) in the central region but firmer where the core transitions from the relatively soft strip to the relatively hard tube. The leading edge of the sheet material imbeds itself into the soft central region of the strip as additional layers are wound around the core.

A safety chuck mounted to equipment that process web material is provided. The safety chuck is provided with a die spring connecting a moveable jaw with a spindle, said spring urging the moveable jaw into a fully closed position. A number of magnets mounted on a mounting flange will engage the moveable jaw, overcoming the spring's force and holding the moveable jaw in a fully open position. Rotation of the spindle releases the magnets allowing the spring to force the moveable jaw back into a fully closed position.
