Problems solved by technology

In contrast, in polyester tapes, the notch strength in the width direction is low because fibrillation does not significantly develop in the length direction even when stretched.
The result is, as Figure 14 Shown, easy to crack in the width direction
Therefore, in the roll body using the method of completely penetrating the thermoplastic resin tape made of polyester, there is a possibility that the tape may break when tightening a heavy package by a baler or when transporting a heavy package.

Embodiment approach 1

[0045] figure 1 It is a diagram for illustrating the configuration of the main part of the first embodiment of the present invention in a time-lapse manner, figure 2 is a cross-sectional view showing a state in which the speaker penetrates a thermoplastic resin tape in the first embodiment of the present invention, image 3 It is a figure showing the loudspeaker applied to the embodiment of the present invention, and FIG. 4 is an action explanatory view of the first embodiment of the present invention, Figure 5 It is a figure for showing the manufacturing method of the roll body which concerns on 1st Embodiment of this invention with time.

[0046] In this manufacturing method, the winding of the thermoplastic resin tape 11 is performed using the core body 2 and the ultrasonic welding machine 1 . On the ultrasonic welding machine 1, the setting is image 3 Cylindrical speaker 10 as shown. The front end 10a of the loudspeaker 10 is flat, and its diameter is preferably le...

Embodiment approach 2

[0055] In this embodiment, a method for manufacturing a coreless roll body in the case of using a polyester tape as the resin tape used for packing heavy objects will be described.

[0056] As described above, polyester tapes are prone to tearing in the width direction because of the characteristic that fibrillation does not develop in the longitudinal direction like polypropylene tapes. In such polyester tapes, such as Figure 5 The manufacturing process shown differs from the method of welding using the ultrasonic welding machine 1 . The speaker 10 used here has a cylindrical shape with a flat front end surface. In addition, considering the upper limit of the peel strength, the diameter of the speaker 10 is 2 mm or less. The ultrasonic welding machine 1 having such a speaker 10 is used. Image 6 It is a figure which shows the structure of the main part for demonstrating the lapse of time of 2nd Embodiment. In addition, since it is the same as that of 1st Embodiment excep...

Abstract

A method for producing a thermoplastic resin string roll of the present invention uses a core made of a plurality of core pieces that are arranged along a circumference and can move back and forth in a diameter direction, the outer faces of the core pieces forming a part of a cylinder when the core pieces are extended in the diameter direction. The end of a thermoplastic resin string is fixed, while the core pieces of the core are extended in the diameter direction. Then, the core is rotated to wind the thermoplastic resin string a plurality of times around the periphery of the core. Thereafter, supersonic vibration is applied to a plurality of layers of the thermoplastic resin string that is wound round the core via a horn, thereby causing frictional heat, so that the plurality of layers of the thermoplastic resin string are connected by thermal fusion due to the frictional heat, and then the thermoplastic resin string is wound to produce a roll. The plurality of layers of the thermoplastic resin string are connected by inserting the horn in the thermoplastic resin string and drilling while melting.

Description

technical field [0001] The present invention relates to a method for manufacturing a thermoplastic resin tape roll, and more specifically, to a method for manufacturing a thermoplastic resin tape roll without a winding core. technical background [0002] As a method of manufacturing a roll body of a thermoplastic resin tape without a winding core, there is a method disclosed in JP-A-2000-344422. In this method, through-holes are provided in overlapping resin tapes inside the coils, and the resin tapes are connected by fusing the peripheral edge portions of the through-holes. As a method of forming a through-hole in this way and fusing it, the following method is disclosed, that is, in the middle of the winding process, a heating needle is used to penetrate the diameter direction from the center side of the coil to fuse it, or the method of using ultrasonic Welding method etc. [0003] In methods using heated needles, such as Figure 15 As shown, the heating needle 109 is p...
