Abstract
The present invention provides a conveyor belt tracking system for a dryer having a web of a mesh material having a protrusion extending along the length proximal one lateral edge and above a flat surface and a first generally cylindrical roller having a three-tiered slot for receiving the protrusion and two flanking shallow tracks for receiving base flanges.
Claims17
A dryer comprising:
- a dryer housing having an input opening to a drying chamber and an output opening from the drying chamber;
- a drive roller mounted to the dryer housing for rotational motion about an axis;
- an idler roller mounted to the dryer housing and spaced from the drive roller;
- an annular groove on one of the drive roller or the idler roller spaced inwardly from a lateral edge of the drive roller or the idler roller;
- and
- at least one belt extending through the drying chamber entrained about the drive roller and the idler roller for reciprocal translational movement between a first position proximate the input opening outside the dryer chamber to a second position proximate the output opening outside the drying chamber in response to rotation of the drive roller, the belt having a protuberance extending above a surface of the belt and extending along a portion of a length of the belt and positioned in the groove.

A textile dryer comprising:
- a dryer housing having an input opening into a drying chamber and an output opening from the drying chamber;
- a heating element within the housing, the heating element being at least one of a gas heater, electric heater, or an infrared radiant heating element;
- and
- at least one belt extending through the drying chamber having a heat-resistant, polytetrafluoroethylene-coated fiberglass mesh and entrained about two rollers to define a conveyor, the belt having at least one continuous, longitudinal bead spaced axially inwardly from an outer lateral edge of the belt and facing the two rollers and one of the rollers having at least one guiding groove therein for cooperating with the longitudinal bead for maintaining alignment of the belt as it travels.
