DEVICE OF CUTTING BOTH SIDE WITH TAPER SHAPE ON RIBBON TYPE PAPER TAPE FOR WINDING PAPER CORE}

The present invention relates to a device for processing both ends of the outer shell layer for paper tubes, and more particularly, to improve the connection force and improve the tensile strength and hardness of the outer shell in the butt continuous connection of the shell wound spirally on the outer circumferential surface of the soft core. The present invention relates to a cutting device for both ends of the ribbon-shaped outer shell layer for paper tubes to prevent irregularities from occurring.

The winding paper pipe is for storing and moving the wound material such as paper, film paper, fabric fabric or thread in a wound state.

When the branch pipe is generally cylindrical in shape and has a long length, continuous bonding of paper of a predetermined width and thickness is performed in a connected state, so that a cylindrical structure of a predetermined length is produced, and the overlapping adhesion is repeated for a predetermined thickness. Use of a chemical adhesive is used.

In the case where the wound to be wound on the branch (WIND) is required to maintain the flatness (FLATNESS) on the surface in the unwinded unwinded state, for example, it is highlighted as photo paper, film paper, in particular, next-generation flat panel display In the case of an IT film used for a thin film transistor (TFT) liquid crystal display (LCD), there should be no pressing or transcription marks.

Pressing marks generated on the wound are generated from, for example, bubbles, blisters, foreign matters, irregularities, contamination, scratches, joints, end jaws of the wound, and the like. It is transferred and continuously produces defects.

Therefore, when the wound wound on the branch pipe is unwinded, there is a problem of treating the up to a predetermined length at which the pressed mark is transferred to the defect as a defect.

In order to solve such a conventional problem, a technique of forming a cushion layer (CUSHION LAYER) on the outer circumferential surface of the cylindrical paper tube to prevent the pressed marks from being absorbed and transferred is disclosed in European Patent Publication No. 0598372A1 (May 25, 1994) “Cylindrical composite paperboard cushion core and process for producing same.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional structural view of a wound branch pipe according to the prior art.

Referring to FIG. 1, the structure of the wound paper tube according to the related art will be described. A cylindrical composite paper board cushion core 1 (hereinafter referred to as a “paper tube”) may be a cylindrical paper board substrate ( The cushioning layer 3 is formed on the outer surface of the cylindrical paperboard substrate 2.

2 is a cross-sectional view showing a state in which a wound is wound on a wound paper tube according to the prior art.

Referring to FIG. 2, the branch pipe 1 according to the prior art will be described in detail. The terminal edge 6 of the sheet material 4 (hereinafter, referred to as a 'winding material') ( Since the stepped end is buried in the cushion layer 3, a stepwise mark is not formed, and the stepped layer mark is not transferred to the wound 4.
