Abstract
A tape processing device has a feed device, a cutter assembly, and a coating device. The feed device feeds a tape having a layer of an adhesive. The cutter assembly has at least one cutting blade and cuts the tape. The coating device applies an adhesion-preventing liquid on the at least one cutting blade of the cutter assembly to thereby prevent any of the tape and the adhesive of the tape from adhering to the at least one cutting blade of the cutter assembly.
Claims20
A tape processing device comprising:
- a feed device for feeding a tape having a layer of an adhesive;
- a cutter assembly for cutting the tape, the cutter assembly having a first and a second cutting blade each defining an inner surface and a cutting edge, the first cutting blade being fixed and the second cutting blade being movable relative to the first cutting blade between a first position before a cutting operation and a second position after the cutting operation, the inner surfaces of the first and second cutting blades facing and at least partly contacting each other when the second cutting blade is in the second position;
- and
- a coating device including a reservoir for containing an adhesion-preventing liquid, the reservoir being fixedly disposed with respect to the first cutting blade and contacting the cutting edge of the second cutting blade when the second cutting blade is in the second position, the reservoir being operable to dispense the adhesion-preventing liquid when contacted by the cutting edge of the second cutting blade, whereby the adhesion-preventing liquid is diffused by a capillary action and coats the inner surfaces of the first and second cutting blades when the second cutting blade is in the second position.
A tape processing device comprising:
- a feed device for feeding a tape having a layer of an adhesive;
- and
- a cutter assembly for cutting said tape, said cutter assembly having a fixed blade and a movable blade each having a cutting edge and cooperatively performing a cutting operation by sliding of said cutting edge of said movable blade past said cutting edge of said fixed blade,
- wherein at least one of said cutting edges of said fixed and movable blades is curved to have an outward curvature in a direction of said cutting operation, and wherein an angle formed between said cutting edges of said fixed and movable blades at an intersecting point of the cutting edges progressively increases from about 10 degrees at a starting position to about 13 degrees at a terminating position of the cutting operation.
A tape processing device comprising:
- a feed device for feeding a tape having a layer of an adhesive;
- a cutter assembly for cutting said tape, said cutter assembly having a plurality of cutting blades including a fixed blade and a moveable blade cooperatively performing a cutting operation;
- and
- a static eliminator brush fixed to said fixed blade, the static eliminator brush being in continuous contact with the tape during the feeding of the tape through the cutter assembly.
