Abstract
In one embodiment, a biased fabric is supplied. The biased fabric supply has a first specified width and a first bias angle of warp yarns relative to weft yarns. At least one overfeed roller configured to overfeed fabric from the biased fabric supply at an overfeed rate is provided. At least one spreading arm configured to stretch the fabric to a second specified width and a fabric oven configured to heat the biased fabric supply to a specified temperature and output a balanced crimp and/or elongation biased fabric are also provided.
Claims25
A method, comprising the steps of:
- receiving a fabric of a first specified width, the fabric comprising fibers oriented in a warp direction and a weft direction at a first specified angle relative to one another;
- overfeeding the fabric at an overfeed rate;
- extracting the overfed fabric at a specified feed rate, the overfeed rate exceeding the specified feed rate;
- stretching the extracted fabric to a second specified width;
- and
- heating the stretched fabric to a specified temperature.

A system, comprising:
- an input roller configured to provide a biased fabric supply, the biased fabric supply having a first specified width and a first bias angle of warp yarns relative to weft yarns;
- at least one overfeed roller configured to overfeed fabric from the biased fabric supply at an overfeed rate;
- at least one tenter frame configured to extract the fabric from the overfeed roller at a specified feed rate;
- at least one spreading arm configured to stretch the fabric to a second specified width;
- and
- a fabric oven configured to heat the biased fabric supply to a specified temperature and output a balanced biased fabric;
- wherein the overfeed rate exceeds the specified feed rate and the balanced biased fabric having warp yarns and weft yarns having a substantially similar crimp and a second bias angle of warp yarns relative to weft yarns.
4 more elements
A system, comprising:
- means for receiving a fabric of a first specified width, the fabric comprising fibers oriented in a warp direction and a weft direction at a first specified angle relative to one another;
- means for saturating the received fabric in a fluid;
- means for extracting excess fluid from the saturated fabric;
- means for overfeeding the excess fluid-extracted fabric at an overfeed rate;
- means for extracting the overfed fabric at a specified feed rate, the overfeed rate exceeding the specified feed rate;
- means for stretching the fabric to a second specified width;
- and
- means for heating the stretched fabric to a specified temperature.
