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.
Claims38
An industrial fabric comprising:
- a plurality of infinity coils having a CD length equivalent to the fabric width, said coils arranged such that one of first and second loops of a first infinity coil interdigitates with one of first and second loops of an adjacent infinity coil so as to form a single passage;
- a pintle extending through the passage;
- and
- one or more infinity coils added to said first infinity coil or adjacent infinity coil until the required MD length of the fabric is achieved.
1 more element
An industrial fabric/belt comprising:
- a plurality of infinity coil elements, each of said infinity coil elements having a first loop and a second loop;
- wherein second loop of a first infinity coil element, having an open interior portion, and first loop of the second infinity coil element, having an open interior portion, are interdigitated such that the open interior portions of the second loop of the first infinity coil element at least partially aligns with first loop of the second infinity coil element to form a passage therethrough;
- and
- a pintle disposed in the passage formed by the aligned loops to join the first infinity coil element to the second infinity coil element.
1 more element
An industrial fabric comprising:
- a plurality of coil materials 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.
A coil comprising:
- at least one infinity coil element comprising a plurality of loops, each of the loops having an axis parallel to and collinear with the axis of each of the other loops of the plurality of loops;
- wherein, when viewed parallel to an axis of one of the plurality of loops, each of the plurality of loops forms a closed curve with a respective open interior portion.
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, each of the loops having an axis parallel to and collinear with the axis of the coil;
- 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.
2 more elements
A coil element 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.
A coil element 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.
