A cutting plotter includes a cutting plotter shell, a placement plate disposed outside the cutting plotter shell, an upper transmission assembly and a lower transmission assembly disposed at two ends of the cutting plotter shell, and a belt assembly disposed in the cutting plotter. The lower transmission assembly and the upper transmission assembly correspond to each other to assist paper in entering the cutting plotter. A slide rod is disposed in the cutting plotter shell and located at the top of the upper transmission assembly, and a cutting tool assembly is disposed on the slide rod. The belt assembly includes a driving motor. A belt body is steered through a steering belt wheel of the belt assembly, and the distance between parallel parts of the belt body is decreased through two small-radius tensioning belt wheels, such that the chain installation space is reduced and the cutting plotter is compact.

A feed and cutting unit for selectively cutting and dispensing individual weight material segments from a common strip of backing material is disclosed. The feed and cutting unit comprises a feed assembly, a sensor and a cutter member. The feed assembly includes a drive roller and a follower roller that frictionally engages first and second surfaces of a strip of weight material to selectively move the strip of weight material to a cutter member. The sensor is connected to a controller and measures an amount of segmented weight material on the backing material as the strip of weight material moves past the sensor. The cutter member is actuated to separate weight material segments from the backing material by cutting at least a portion of the backing material in a gap disposed between adjacent segments. Weight apply devices that receive the segments for application to an imbalanced member, are also disclosed.

A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.

An apparatus and a method for dispensing discrete sections of double-sided adhesive tape, comprising a reel support unit whose position is adjustable so as to vary a length of the section of double-sided adhesive tape to be dispensed.

A window insulation apparatus includes a cylindrical core having opposite top and bottom ends. A plastic sheet has opposite top and bottom ends and is pleated along parallel fold lines that extend parallel to the top end of the sheet to form a folded sheet. Adhesive is applied adjacent the top end of the sheet. The folded sheet is wound around the cylindrical core so that the top end of the folded sheet is near the top end of the cylindrical core. A housing receives the core and the sheet wound on the core. The housing includes an elongate opening from which the sheet can be unwound. A cutting assembly is mounted to the housing substantially adjacent the elongate opening and can be moved parallel to the opening for cutting the sheet that has been dispensed from the opening.

A dispenser for dispensing sheet product is provided. The dispenser includes a housing with an outlet through which sheet product is dispensed. A knife drum is rotatable with respect to the housing. A knife is movable between a retracted position within the knife drum and an extended position where the knife protrudes outside of the knife drum to cut the sheet product. A cam follower surface is fixed with respect to the housing. A cam follower is attached to the knife and operable to engage the cam follower surface and travel therealong to transition the knife between the retracted position and the extended position. A spring assembly biases the knife drum during rotation toward a predetermined position. The spring assembly comprises a first spring and a second spring. The spring assembly is attached at a single mount position that is fixed with respect to the housing.

A roll-dispensed stock container is provided. The roll-dispensed stock container has a recessed cutting track and can be assembled by computer aided manufacturing processes.

A nonwoven fabric dispenser is provided with fixation elements attached to the body of the dispenser and a cutter assembly attached to a lid of the dispenser. Nonwoven fabric stock is secured by the fabric engagement structures when the lid of the dispenser is in a closed configuration and the cutter assembly is configured to separate a sheet of the nonwoven fabric stock of a desired length.

A rolled sheet dispenser assembly for dispensing a cutting a selected length of a rolled sheet includes a housing that has a plurality of mounting holes integrated for mounting to a horizontal support surface. The housing has a dispensing slot extending into an interior of the housing to facilitate a rolled sheet positioned in the housing to be drawn outwardly through the dispensing slot. A pair of holders is each of the holders is coupled to the housing to engage a respective end of the rolled sheet. A base is removably attachable to the housing and a cutter is slidably coupled to the base. The cutter is slidable laterally along the base to cut the length of rolled sheet that has been drawn outwardly from the housing.

A wrapping paper storage and dispensing device comprises a storage housing housing a rotating drum having a plurality of tubular canisters. A fixed longitudinal cutting base and a corresponding blade track supported by two pivoting arms are positioned on one side of the housing. A blade carriage slidingly engages the longitudinal blade track with a sliding ratcheting lock mechanism. The ratcheting lock comprises a retractable blade in the blade carriage which locks in place when the blade is extended through a slit in the blade track. The canisters are formed by cylindrical tubes having a rectangular openings extending along their longitudinal lengths, stationary first end caps, sliding second end caps, and sliding tensioners engaged to the canister between the first end cap and the second end cap.
