Abstract
A napper fabric processing machine is provided having a dynamic zoning assembly to allow the operator to vary the amount of fabric in contact with the workers rolls. This zoning allows the napping, sanding, or sueding of a variety of products that are highly unstable or tension sensitive. This zoning also allows a seamless changeover between napping in double and single acting modes and knit goods, all with any ratio of pile to counterpile rolls.
Claims17
A dynamic zoning assembly in a fabric processing machine, the fabric processing machine including a rotating cylinder and worker rolls supported by the cylinder, the zoning assembly comprising a pair of application bars supporting a pair of rollers adjacent to the cylinder, the rollers supporting fabric and being rotatable with respect to the application bars, the application bars moving the rollers towards and away from a path of the worker rolls for adjusting the amount of fabric contacting the worker rolls.
A zoning apparatus in a fabric processing machine, the fabric processing machine including worker rolls, the zoning apparatus including means for adjusting the amount of fabric contacting the worker rolls, the means for adjusting including a pair of application bars supporting a pair of rollers that are rotatable with respect to each application bar for supporting the fabric, the application bars being rotatable towards and away from a path of the worker rolls for adjusting the amount of fabric contacting the worker rolls.
A method of processing a fabric in a fabric processing machine, comprising:
- providing worker rolls in the fabric processing machine;
- and
- modulating the size of at least one zone of fabric contacting the worker rolls by rotating a shaft which has two gears on it, the gears pivoting respective application bars, each application bar supporting a roller over which the fabric passes.
A fabric processing machine, comprising:
- a cylinder supporting a plurality of worker rolls, the cylinder being rotatable about an axle of the cylinder;
- and
- at least one roller adjacent the periphery of the cylinder for holding a fabric web out of contact with the worker rolls, wherein the roller is moveable relative to a path of the worker rolls to adjust the amount of the fabric web in contact with the worker rolls.
A fabric processing machine, comprising:
- a cylinder supporting a plurality of worker rolls, the cylinder being rotatable about an axle of the cylinder;
- and
- two rollers adjacent the periphery of the cylinder for holding a fabric web out of contact with the worker rolls to define three zones of contact between the fabric web and the worker rolls on the cylinder, wherein the rollers are moveable relative to a path of the worker rolls on the cylinder to adjust a size of the zones of contact.
