Shoe press belt and manufacturing method

A method of manufacturing a shoe press belt comprising the steps of winding a belt-shaped member having a starting end, a terminal end and parallel side edges, and having the ability by itself to resist both lateral and longitudinal stretching, onto a support body having a cylindrical surface in multiple layers, with the side edges of the belt-shaped member disposed substantially in planar spirals, and forming, from a resin, a Cylindrical, high molecular weight elastic member on the base member so that the elastic member has a wall thickness, so that the base member is embedded within the wall thickness of the elastic member, and so that every point on said starting end is adjacent to a point on said terminal end.

A shoe press belt comprising a cylindrical, elastic member formed of a high molecular weight resin and having a base member embedded therein, the cylindrical member having inner and outer walls coaxially disposed about an axis, the inner and outer walls being uniformly spaced from each other radially, whereby the cylindrical member has a uniform thickness, and the base member embedded in the high molecular weight resin being located between the inner and outer walls of the cylindrical member and comprising a belt-shaped member having parallel side edges, the belt-shaped member by itself having the ability to resist both lateral and longitudinal stretching, and being spirally wound in multiple layers, with its side edges disposed substantially in planar spirals, whereby the belt-shaped member of the base has substantially the same width as the belt, the belt-shaped member has a starting end and a terminal end, both said ends being adjacent each other, and both said ends, and the axis of said cylinder, being situated approximately in the same imaginary plane.

A method of manufacturing a shoe press belt comprising the steps of winding a belt-shaped member having parallel side edges and the ability by itself to resist both lateral and longitudinal stretching, onto a support body having a cylindrical surface in multiple layers, with the side edges of the belt-shaped member disposed substantially in planar spirals, and forming, from a resin, a cylindrical, high molecular weight elastic member on the base member so that the elastic member has a wall thickness and so that the base member is embedded within the wall thickness of the elastic member, a starting and a terminal end of the belt-shaped member are caused to be situated adjacent each other in the completed shoe press belt, and said starting and terminal end and the axis of said cylindrical surface, are caused to be situated, in the completed shoe press belt, approximately in the same imaginary plane.
