る熱接着装置がある（第５図ａ，ｂ）。(Prior art) Conventionally, as a technology for thermally bonding the edges (sides to be bonded) of two layers of polyester film stacked together for the production of polyester film bags, etc.
For example, as seen in Japanese Patent Publication No. 58-38297 ``Thermal bonding method of polyester film'', clamping support plates A and B of a certain length are used to clamp and support two stacked polyester film pieces A. Clamping devices installed on the top and bottom, clamping support plates (a) and (b) for applying the required heat to the outwardly protruding sides a to be bonded.
There is a thermal bonding device which includes a heating device which brings a heating body C of a constant temperature placed opposite the entire length of the side to be bonded A and a heating device which moves them away from each other (FIGS. 5A and 5B).
係る装置は、ポリエステルフイルム片Ａの被接
着辺ａの長さが挟圧支持板イ，ロの長さ以上ある
場合には直接には対処できず、従つて対象となる
ポリエステルフイルム片Ａの大きさに制限があつ

着辺ａに対して接近、離反作動なる反復作動を以
つて一熱接着処理が完了されるものであるから連
続した熱接着処理をすることができないなどの問
題があつた。 Such a device cannot directly deal with the case where the length of the side a to be adhered of the polyester film piece A is longer than the length of the clamping support plates A and B; There were limits to this. Furthermore, the polyester film piece A is set in the clamp device once at a time, and the heating element C repeatedly approaches and moves away from the side A to be bonded, thereby completing the heat bonding process continuously. There were problems such as the inability to perform thermal adhesive treatment.

を目的とする。(Problems to be Solved by the Invention) This invention is capable of continuous thermal bonding, and is capable of thermal bonding not only regular length polyester film pieces, but also particularly long polyester film pieces with irregular lengths. The purpose is to make it easier, smoother, and more efficient.

Taking into account the shrinkage of the bonded side a, the bonded side has a certain distance relationship with respect to the bonded side a. In the embodiment shown in the drawings, the rod-shaped heating element 4 is inclined, but the endless belts 1 and 2 may be made to run diagonally, or the heating surface 4a of the rod-shaped heating element 4 may be formed as an inclined surface. . Reference numeral 8 indicates an air jetting means for cooling the side to be bonded a after melting and fusion bonding.

のは厚手フイルムの場合に好ましい。 The heating element 4 is heated to a constant temperature using a heating means such as a nichrome wire. The temperature is set at a relatively low temperature at which melting begins. The heating body 4 has a heating surface 4 having an appropriate shape depending on the thickness of the film piece A.
Film a was selected, and its various cross-sectional shapes are shown in sections 4a, b, c, and d. In the figure, film d is preferable for thick films.

なる。(Function) Two overlapping polyester film pieces A
, the endless belts 1, 2 of the contact/separation means 3 such that the adhered side a protrudes outside the endless belts 1, 2 by a required width.
When it approaches and passes the heating body 4 of the heating means 5 while being pinched and supported by the running of the endless belts 1 and 2, the side to be adhered a is heated from its leading portion. Due to this heating, the side to be bonded a
gradually melts from the leading part, and this melting causes shrinkage in the adhered side a, and this shrinkage increases as the film piece A advances, but the heating surface 4a of the heating element 4 The distance from the side to be bonded a gradually decreases from the heating start portion to the heating end portion, and at the heating end portion, the heating end portion is set to apparently overlap with the bonding side a, so that from the heating start portion to the heating end portion. The distance between the heating surface 4a of the heating element 4 and the side to be bonded a remains the same until the end of heating, and therefore the temperature of the side to be bonded a does not decrease and heating is performed at a constant temperature from the very vicinity of the side to be bonded a. will be done. As a result, the melting speed of the welding surface of the adhered side a (the bonding surface of the upper and lower film pieces A) is made constant, and the maximum temperature of the melted and fused portion is also made constant.

溶融融着した被接着辺ａは空気噴出手段８により
急速に冷却されるのである。 In this way, the side to be bonded a passes along the heating surface 4a of the heating element 4 to the heating end portion without contacting it, thereby forming a melted and fused portion of an appropriate width on the side to be bonded a. It is. Then, the bonded side a separates from the heating body 4, and the melted and fused bonded side a is rapidly cooled by the air jetting means 8.
このようにして溶融固化した被接着辺ａには熱
分解が起こらず、断面均一に溶融融着されて接着
力の大きい熱接着が得られる。 No thermal decomposition occurs on the bonded side a that has been melted and solidified in this manner, and is melted and fused uniformly in cross section, resulting in thermal bonding with high adhesive strength.

奏する。(Effects) In this invention, the thermal bonding process is carried out continuously by feeding the film pieces between the belt surfaces of the endless belt, so even long film pieces of varying length can be easily and smoothly fixed to the specified length. It is possible to heat-bond film pieces one after another efficiently without interruption, and the above-mentioned thermal bonding can be performed by heating at a constant low temperature from very close to the edges to be bonded, taking into account the shrinkage of the edges to be bonded. Adhesion that does not deteriorate and has high mechanical strength can be obtained, and has advantages such as good workability.
