Abstract: A cutting structure for plastic film includes a bracket, a first roller, a second roller, a tachometer, a processor, a monitor and a cutter. The bracket includes a bottom and two sidewalls extending from the bottom along a same direction. The first roller includes a shaft fixed to the sidewalls and a sleeve rotatably sleeving on the shaft. The second roller is pivotally connected to the sidewalls. The tachometer is disposed on one end of the second roller and configured for measuring the rotation speed of the second roller. The processor is configured for reading the rotation speed and further calculating a rotation distance of the second roller. The monitor is configured for displaying the rotation distance. The cutter extends upward from the bottom for cutting the plastic film pulled from the first roller and the second roller.

Abstract: An electrically powered tape dispenser device has a housing with a base and a top cover that opens to allow placement and removal of a tape roll supply within a tape well. Operation of a push button control actuates a motor and a pinch roller assembly to drivingly engage and pull a tape segment of select length from the roll supply for dispensing through an open mouth of the housing. The dispensed tape segment is separated from a remainder of the supply by a cutting blade fixed to the housing at the mouth. The tape segment length is preset by pushing a “count up” button to increase length or a “count down” button to decrease length. Another embodiment provides the additional function of dispensing adhesive-backed labels or stamps (e.g. postage stamps) from a roll. A lever is provided to move the pinch roller assembly into engagement with a backing strip that is pulled from the stamp roll, causing one or more stamps to be separated from the backing strip and dispensed through a stamp chute.

Abstract: A sheet material product includes a length of substantially planar material with a series of linear scale indicia applied along the length of the substantially planar material, and a dispensing member adapted for retaining and dispensing the length of the material, the dispensing member further including a reference indicator in operative association with the series of linear scale indicia to indicate the amount of the material dispensed and/or the amount of the material remaining in the dispensing member.

Abstract: A cutter for cutting flexible material held on a roll thereof. The cutter has a frame that mounts a drop in roll of flexible material and a drop in tensioning roller in an open end of the frame. The cutter has a cutting area that is generally enclosed and houses a plurality of slitting knives and a tear off cutting blade. The cutting area has an entrance and exit slot for the material with the slitting knives slitting the material as it passes through the cutting area. The slit material can exit through the exit slot. After a predetermined length has been pulled forwardly relative to the cutting blade the slit material can be cut into pieces by tearing it against the cutting blade. A length determining gage allows pieces of a precise length to be cut. The material is pulled through the cutter by a set of feed rollers contained within the cutting area.

Abstract: The invention provides a longitudinally extending adhesive tape product adapted to be cut off into a plurality of tape segments by use of a transverse cutting edge. The product comprises a longitudinally extending tape wound into a roll, the tape having a first side which is adhesive free, a plurality of longitudinally separated indicia and a second side which has a corresponding plurality of longitudinally separated and transversely extending coating bands of pressure sensitive adhesive. The coating bands have leading and trailing edges and are separated by portions of the second side of the tape which are substantially adhesive free. The indicia are so located relative to the coating bands whereby when one of the indicia is aligned in a specified relation to the cutting edge and a tape segment is cut off, the cut off tape segment has a single one of the coating bands and the coating band on the cut off tape segment is located adjacent a transverse edge of the tape segment.

Abstract: In a motor-driven tape cutter including a cavity formed longitudinally on the upper side of a cutter body, a reel provided at one end of the cavity for supporting a ring-like roll of adhesive tape, a feed roller provided at the other end of the cavity for peeling and reeling out the leading end of the adhesive tape over a predetermined length, a backing roller and a presser roller adapted to grip the unreeled tape portion from opposite sides for straightening warping of the tape, a cutter blade for cutting the unreeled tape portion, a motor for driving the feed roller and the backing roller, a switch for actuating the motor, and a switch operating member which closes the switch in response to a tape cutting operation thereby reeling out a predetermined length of the ensuing tape portion, a cutter blade holder pivotally mounted on the front side of the cutter body to cover a fore end portion of the body cavity and at least part of the feed, backing and presser rollers and mounting the cutter blade and presser

Abstract: A wallpaper preparation board made of low cost rigid sheet material such as cardboard, paperboard, thin wooden, metal, or plastic sheets, etc., is formed from a plurality of substantially flat panels of the sheet material which are hingedly attached end-to-end to form an elongate board which can be folded in accordion style into a compact unit. A pair of hooks 11 and 12 are provided at the top of the board, with the hooks being adapted to engage the top of a door or the edge of the top landing of a ladder, so that the board can hang downwardly from the door or the top of the ladder. A pair of ears project upwardly at opposite sides of the upper end of the board to receive the opposite ends of a rod which is inserted through a roll of wallpaper. A knife edge extends across the board near the roll of wallpaper to aid in cutting lengths of wallpaper which are withdrawn from the roll.
