Belt connecting method, presetter, and belt connecting apparatus
First Claim
1. A flat belt connecting method for forming an endless connection of a flat belt by using a presetter, comprising the steps of:
- setting so that the connecting portions at both ends of the flat belt are placed on a lower mold surface of the presetter, and that, with the flat belt held from both sides by a wall part standing from the lower mold surface and a flat belt member having substantially the same compression property as the flat belt, an upper mold of the presetter is placed on the flat belt and the flat belt member, and then fixing the flat belt and the flat belt member by the presetter; and
connecting the connecting portions at the both ends by pressing the presetter with the flat belt and the flat belt member fixed.

Abstract
A method for enabling a presetter to connect connecting portions of belts having different widths, and for forming an endless connection of a flat belt with no defects such as the bend of the connecting portions. This method includes a first step of setting so that the connecting portions at both ends of the flat belt are placed on a lower mold surface of the presetter, and that, with the flat belt held from both sides by a wall part standing from the lower mold surface and a flat belt member having substantially the same compression property as the flat belt, an upper mold of the presetter is placed on the flat belt and the flat belt member, and then fixing the flat belt and the flat belt member by the presetter; and a second step of connecting the connecting portions at the both ends by pressing the presetter with the flat belt and the flat belt member fixed.

11. A presetter for use in forming a connection of a flat belt, comprising:
-
a lower mold that is used to place connecting portions at both ends of a flat belt and a flat belt member having substantially equivalent compression property as the flat belt; a wall part that stands from one side of the lower mold and holds the connecting portions at the both ends of the flat belt from both sides, along with the flat belt member, an upper mold placed on the connecting portions at the both ends of the flat belt and the flat belt member; and fixing means for firmly fixing the connecting portions at the both ends of the flat belt and the flat belt member. - View Dependent Claims (12, 13, 14)

15. A flat belt connecting method for forming an endless connection of a flat belt by using a presetter, comprising the steps of:
-
placing connecting portions at both ends of the flat belt on a surface of a lower mold of the presetter; holding the flat belt from both sides by a stationary wall part and a movable wall part that stand from the surface of the lower mold; fixing the flat belt by placing an upper mold of the presetter whose width is adjusted so as to conform to a width of space in between the stationary wall part and the movable wall part, on an upper surface of the flat belt held between the stationary wall part and the movable wall part; and connecting the connecting portions at the both ends by pressing the presetter with the flat belt fixed. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A toothed belt connecting method for forming an endless connection of a toothed belt by using a presetter, comprising the steps of:
-
placing connecting portions at both ends of the toothed belt on a surface of a lower mold of the presetter; holding the toothed belt from both sides by a stationary wall part and a movable wall part that stand from the surface of the lower mold; placing a resin sheet for melt bonding and an intermediate member on the connecting portions at the both ends and surroundings thereof in the toothed belt; fixing the toothed belt and the resin sheet and the intermediate member by placing an upper mold of the presetter whose width is adjusted so as to conform to a width of space in between the stationary wall part and the movable wall part, on an upper surface of the intermediate member; and connecting the connecting portions at the both ends by pressing the presetter with the toothed belt and the resin sheet and the intermediate member fixed. - View Dependent Claims (23)

24. A presetter for use in forming a connection of a belt, comprising:
-
a lower mold having a flat surface part, a stationary wall part and a movable wall part that stand from the flat surface part and hold from both sides connecting portions at both ends of a belt; and an adjustable length upper mold that fixes the flat belt together with the upper mold by inserting at least a bottom surface part into space in between the stationary wall part and the movable wall part. - View Dependent Claims (25, 26, 27)
