Detailed description of the invention
Embodiment 1: have angle to have the production method of the adhesive tape product in gap.
See Fig. 4, continuous adhesive tape 20 is unreeled by upper emptying roller 23 and to be carried by upper feeding roller 24 afterwards, and continuous release layer band 10 is unreeled by lower emptying roller 13 and to be carried by lower feeding roller 14 afterwards.What upper feeding roller and lower feeding roller paralleled is oppositely arranged up and down, the continuous adhesive tape 20 be transferred and being with between upper feeding roller and lower feeding roller by the continuous release layer 10 that lower feeding roller is carried.
The continuous adhesive tape of upper feeding roller conveying and the continuous release layer band of lower feeding roller conveying are admitted to the cross cutting platform 3 of die-cutting machine jointly.The top of cross cutting platform 3 has the cutting knife 4 moved back and forth up and down.The blade 41 of cutting knife is two sections of connected angled straightway blades.Cutting knife moves down, and cutting knife blade cuts off continuous adhesive tape.When cutting knife cuts off continuous adhesive tape, upper feeding roller and lower feeding roller all stop operating, continuous adhesive tape 20 and continuous release layer 10 all motionless.When cutting knife cuts off continuous adhesive tape, see Fig. 5, because blade is two sections of connected angled straightway blades, so the cut channel 5 between cut-off adhesive tape unit 21 and continuous adhesive tape 20 is broken line, the side of adhesive tape unit 21 with adhesive tape unit 21 angled tear hand 26.
Upper feeding roller and lower feeding roller are intermittent rotaries, and when cutting knife cuts off continuous adhesive tape, upper feeding roller and lower feeding roller do not rotate.In the time period that the twice pair of continuous adhesive tape cuts off before and after cutting knife, upper feeding roller and lower feeding roller all rotate, but the linear velocity that upper feeding roller rotates is less than the linear velocity that lower feeding roller rotates, and makes the fed distance of feeding roller to continuous adhesive tape be less than the fed distance of lower feeding roller to continuous release layer band.Such as, the time moved back and forth from bottom to top is once 0.2 second to cutting knife from the top down, again, and cutting knife moves back and forth once, again moves back and forth through 0.5 second.In 0.2 second that moves back and forth at cutting knife, upper feeding roller and lower feeding roller all do not rotate.Before and after cutting knife in the adjacent 0.5 second time interval moved back and forth for twice, upper feeding roller and lower feeding roller all rotate, feeding roller is made to be 1.5mm to the fed distance of continuous adhesive tape, the fed distance of lower feeding roller to continuous release layer band is 2.6mm, namely during each mobile 1.5mm of continuous adhesive tape, each mobile 2.6mm of continuous release layer band.
See Fig. 6,7, the adhesive tape unit 21 cut off is attached on continuous release layer and moves with continuous release layer, but the distance due to continuous release layer movement is greater than the displacement of continuous adhesive tape, so adhesive tape unit just and between continuous adhesive tape produces gap 25, this gap width is exactly difference and the 1.1mm of continuous release layer displacement and continuous adhesive tape displacement.Certainly, the width of each adhesive tape unit is exactly the distance of continuous adhesive tape movement at every turn, i.e. 1.5mm.
The continuous release layer band 10 being pasted with adhesive tape unit 21 is wound on wind-up roll 5, namely obtains the adhesive tape product that angle has gap, see Fig. 8 through cutting.Described angle refers to the angle of tearing hand 26 and being formed with adhesive tape unit 21.
The individual layer adhesive tape layer that described adhesive tape layer can be made up of individual layer adhesive tape unit (certainly, continuous adhesive tape is individual layer continuous adhesive tape), the MULTILAYER COMPOSITE adhesive tape layer (certainly, continuous adhesive tape is MULTILAYER COMPOSITE continuous adhesive tape) that also can be made up of MULTILAYER COMPOSITE adhesive tape unit.
This has angle to have the production method of the die cutting of adhesive tapes product in gap, and production efficiency is high, reduces the waste of die cut material and labor hour.This have angle have the die cutting of adhesive tapes product in gap paste liquid crystal display time more convenient to operate.
