Abstract: An adhesive tape dispenser is comprised of a dispensing body that provides for the loading of a roll of tape at its rear portion and a blade mounted on the dispensing body. A roller, a guide wheel, and a pawl are respectively pivotally mounted in the dispensing body. The roller has a plurality of protrusions arranged around one end thereof. The pawl has a pressing member capable of positioning against the circumferential face of the roller as well as an engaging portion capable of becoming engaged between two protrusions of the roller, and the pawl is postured to the rear by an elastic member. Tape is inserted between the roller and the pawl and then routed pass the guide wheel to the area of the blade and when it is applied forward, the roller correspondingly rotates forward in the same direction and the protrusions allow the engaging portion to slide over them.

Abstract: A heat sealing jaw assembly for effecting a heat seal of at least two juxtaposed heat sealable sheet materials is described. Preferably, but not exclusively, the heat sealing jaw assembly is adapted for use in a form, fill and seal machine forming thermoplastic bags. The heat sealing jaw assembly comprises a first and a second metal jaw member, each having a heating element for heating the jaw members. Each of the jaw members has an end face disposed in facial alignment with one another. A ribbon member is secured to each of the end faces and disposed in planar alignment with one another. The ribbon member is made of soft material having rubber-like properties and capable of conducting heat from the sealing jaw to a fusing temperature to melt the heat sealable sheet materials.

Abstract: A hand-held tape dispenser with tape positioning structure mainly includes a tape reel from which a length of tape is dispensed and applied onto a surface, and a holding-down plate adapted to push a blade below it to cut the dispensed tape. The tape positioning structure includes two L-shaped plates fixed to two sides of the blade. Each of the two L-shaped plates has a hooked front end exposed from one side of a front plate located below the blade. When the blade is pushed forward to cut the dispensed tape, the hooked front ends of the L-shaped plates move forward at the same time to hook up a free end of the cut tape, and when the holding-down plate is released and the blade retracts, the cut tape is held by the retracted hooked front ends to the front plate for use next time.

Abstract: A sheet piece (S′) that is needed to assemble wiring harnesses (W) on a harness assembling board (A) is recognized, and a recognition signal is generated. A sheet cutting apparatus (20) then cuts a sheet (S) from a sheet roll to a specified length in accordance with the recognition signal. The cut sheet piece (S′) then is dropped onto the respective harness assembling board (A). The sheet cutting apparatus (20) has a sheet feed roller (22), pressure rollers (23) that are movable toward and away from the feed roller (22) and cutters (26) for cutting the sheet (S). The feed roller (22) is rotated and the pressure rollers (23) press the sheet (S) against the feed rollers (22) in response to the recognition signal. Thus, a specified length of the sheet (S) is fed, and the cutters (26) cut the sheet (S) into a sheet piece (S′) of the specified length.

Abstract: A line slit nozzle for spraying steam is disposed along a diameter of a resist film. Steam containing a mist is sprayed onto a surface of the resist film. The film is thereby peeled off and removed. By using a change in physical properties (swelling, etc.) of the resist film by water, the film is easily and surely peeled off. Breakaway from much resources/energy consumption type techniques is realized. In other words, realized are environment-symbiosis type techniques by which resist films can be removed independently of the quantity of energy and kinds of chemical solvents.
