Abstract
An industrial fabric/belt including spiral coils shaped as a symbol for infinity or a lemniscate, i.e., infinity elements, are joined to each other with a pintle. A fabric element is configured as a continuous loop to form an industrial fabric employing a plurality of infinity coil elements.
Claims13
A coil comprising:
- at least one infinity coil element comprising a first loop, a second loop, and an intersection region wherein the first loop intersects with the second loop, each of the first loops having an axis collinear with the axes of each of the other first loops and each of the second loops having an axis collinear with the axes of each of the other second loops;
- wherein, when viewed parallel to an axis of the first or second loop, each of the first loops and second loops form a closed curve with a respective open interior portion;
- and
- wherein the coil is formed from material selected from the group consisting of:
- a monofilament, twisted multifilaments, and metal wire.
2 more elements
A coil comprising:
- a coil axis;
- an axial length parallel to the coil axis;
- a width perpendicular to the axial length;
- a continuous strand of material formed into a continuous helical plurality of infinity coil elements, each of the plurality of infinity coil elements comprising at least a first loop and a second loop;
- wherein, the axes of the at least first loops are collinear with one another and the axes of the second loops are collinear with one another such that, when viewed parallel to the coil axis, each of the plurality of loops appears to form a closed curve with an open interior portion;
- and
- wherein the coil is formed from monofilament, twisted multifilaments, or metal wire.
4 more elements
A coil comprising:
- a coil material formed as a lemniscate having two closed curves forming first coil loops and second coil loops, the first and second coil loops enclosing respective first and second open interior portions, and an intersection region between the closed curves in which the coil material forming the first coil loop intersects with material forming the second coil loop;
- and
- wherein the coil material is formed from material selected from the group consisting of:
- a monofilament, twisted multifilaments, and metal wire.
1 more element
A coil comprising:
- a coil material formed as three or more closed curves forming three or more adjacent coil loops, the three or more coil loops enclosing respective open interior portions, and intersection regions between adjacent coil loops in which the coil material forming a coil loop intersects with material forming an adjacent coil loop;
- and
- wherein the coil material is formed from material selected from the group consisting of:
- a monofilament, twisted multifilaments, and metal wire.
