s1, when the double-sided tape needs to be used, the feeding driving motor 24 and the discharging driving motor 24 are started by a worker, the double-sided tape moves forwards, the colloid of the double-sided tape faces upwards, the isolation paper is arranged below the double-sided tape, and when the length of the double-sided tape reaches a set value, the single-rod air cylinder 26 pushes the hob cutter 32 to scratch the double-sided tape, and the dotted line scratch is left.

S2, continuing to move the feeding driving motor 24 and the discharging driving motor 24, stopping the forward movement of the double-sided tape when the dotted line scratch passes through the left edge of the movable glue pressing cylinder 8, pressing the adhesive tape by the fixed glue pressing cylinder 6 and the movable glue pressing cylinder 8 in a pressure equalizing manner, driving the movable glue pressing assembly to move leftwards by the driving motor 24, and compensating the adhesive tape by the discharging driving motor 24 moving leftwards; the double-sided tape is folded into a downward V-shaped shape at the right edge of the fixed glue pressing cylinder 6 until the movable glue pressing assembly is attached or basically attached to the fixed glue pressing assembly, so that the glue of the double-sided tape in the folding area of the tape is adhered together, at the moment, the movable glue pressing cylinder 8 loosens the tape and moves rightwards, the double-sided tape is pressed again and moves leftwards when the specified distance is reached, and the discharging driving motor 24 also moves leftwards to compensate the tape; double-sided tape is "W" type this moment at the right marginal double-sided tape of fixed moulding cylinder 6, and the dotted line mar is at the middle part of "W", and it compresses tightly the sticky tape right motion to remove moulding cylinder 8 at last, and ejection of compact driving motor 24 also moves right and evens up the sticky tape, and double-sided tape's colloid uses the dotted line mar to be divided as the center, and the both ends colloid is bonded by "W" adjacent side separately about the dotted line mar, reserves glossy isolation paper face.

S3, after the double-sided adhesive tape is leveled, the feeding driving motor 24 and the discharging driving motor 24 continue to move rightwards, and the shearing mechanism 11 shears the adhesive tape from the broken line scratch.

S4, after the operations, the two ends of the single double-sided adhesive tape can be left with the isolation paper with a certain length, thereby achieving the effect of removing the adhesive at the two ends.
