Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape cutter that manufactures a tape by cutting a cylindrical knitted original fabric in a spiral shape from its end while rotating the tape.

As such tape cutters, those shown in FIGS. 1 and 2 have been known.

The one shown in Figure 1 is a horizontal drum 2 mounted on the top of a frame 1.
The upper end of the raw fabric 4 stored in the bucket 3 at the front of the lower part of the frame 1 is wound around the drum 2, and the raw fabric 4 is rotated by the rotation of the rubber roller 5 and the bucket 3 and fed out at a constant pitch as shown in the figure. It has a structure in which it is cut into a tape shape using a rotary blade (not shown). In addition, as shown in FIG. 2, there is also a method in which the drum 2 is turned downward and the raw material 4 introduced into the drum 2 from the bucket 3 directly below the drum 2 is cut into tape shapes.

However, in the apparatus shown in Fig. 1, since the drum 2 is horizontal, the web 4 guided from the bucket 3 is bent at right angles at the tip of the drum 2, which tends to hinder the feeding of the web and ensure accurate tape. Moreover, the vertical drum 2 shown in FIG. 2 also has the disadvantage that it is difficult to feed the original fabric smoothly.

The purpose of this invention is to solve the above-mentioned drawbacks of the conventional tape cutter, and to provide a tape cutter that can feed the tape extremely easily and produce accurate tape with high efficiency.

That is, the present invention provides a pair of drums that rotate around a diagonally downward axis on a frame, guides the cylindrical knitted raw fabric stored in a bucket at the front of the lower part of the frame upward, and covers both drums. A receiving plate is provided which receives the rotation of the drum and the inside of the original fabric that spans between both drums, and a widening rubber roller that rotates while pressing the original fabric against this receiving plate and feeds out the original fabric at a constant pitch while rotating the original fabric. On the side of this rubber roller, the front edge of the original fabric is cut out in a spiral shape with a fixed number 11 (
The present invention provides a tape cutter equipped with a pair of upper and lower rotating blades.

The details of the tape cutter of the present invention will be explained below based on an embodiment shown in the attached diary.

In FIG. 3, reference numeral 8 denotes a frame bent into an L shape, and a machine box 12 is provided on the front side of the upper part of the frame. Reference numerals 13 and 14 in FIG.
An empty drum 15 is detachably attached to the shaft 14, and a driven drum 16 is fixed to the shaft 14.

17 is a receiving plate fixed to the front part of the machine box 12, and both drums 15.
It supports the lower surface of the upper part between the drums 15 and 16 of the original fabric 1B placed on the drum 16. 19 is also a receiving rod fixed to the front part of the machine box 12, and the stiffening receiving rod 19 supports the lower surface of the lower part of the original fabric 18 between the drums 15 and 16.

Reference numeral 20 denotes a rubber roller 1-1 for feeding, and the shaft of this roller 20 is also connected via a universal joint to the drive shaft coming out of the machine box 12, and this roller 20 presses the original fabric 18 onto the receiving plate 17. The feed amount is adjusted by an appropriate adjustment device, and the rubber roller 20 is attached by changing the corner.

21.22 is a pair of upper and lower rotating blades, and this rotating blade 21.2
2 is also attached to the drive shaft coming out of the machine box 12, and a winding roller 23 is provided on the side thereof.

24 in Fig. 3 is a motor, and this motor 24 causes the machine box 1 to
Driving the transmission mechanism in the drum 160-20.
The rotary blades 21, 22, roller 23, etc. are driven in the direction of the arrow in FIG.

Further, a rotary bag 25 is provided on the front end of the lower part of the frame 11 to place the raw fabric 18, and this bucket 25 is placed on the drum 1.
6, etc., to prevent the original fabric 18 from twisting.

The tape cutter of this invention has the above-mentioned configuration, and is shown in FIG.
As shown in FIG.
16, and drive each part to rotate the raw material and send it out at a constant pitch.
Cut the tape into a spiral shape and roll it up with the roller 23 or store it in a suitable container.

As described above, in the tape cutter of the present invention, the upper end of the tubular knitted raw material 18 is placed on the obliquely downward facing drum 15, 16, and the raw material 18 is rotated by the rotation of the drum 15, 16 and the rubber roller 20 for creaming. While feeding at a constant pitch, the rotary blade 2
1. In step 22, the tape is cut out, but since the drums 15j16 are facing diagonally downward, the original material 1
8 is smoothly fed into the drum 15,16. Therefore, the feeding pitch of the raw material 18 becomes accurate, which has the effect of efficiently cutting a tape of a precise width.
