Abstract
A roll quadrant conveyor for conveying strip material generally includes a plurality of support members for supporting a plurality of rolls around a quadrant roll of any desired wrapping angle and, further, a plurality of rolls journaled for rotation in the support members. The rolls are positioned on opposed sides of a conveyor centerline, with each roll positioned at an angle of less than 90° with the conveyor centerline. The rolls define a chevron pattern around the wrapping angle. The strip material, in motion, is centered on the conveyor by the rolls arranged in the chevron pattern. The rolls are profiled rolls.

A quadrant roll conveyor for conveying strip material around a quadrant roll of any desired wrapping angle, comprising:
- support means;
- and
- a plurality of rolls journaled for rotation in the support means, with the rolls arranged in a plurality of roll pairs, with the respective rolls in the roll pairs positioned on opposite sides of a conveyor centerline, and with the rolls in the roll pairs having separate, straight shafts positioned at an angle of less than 90° with the conveyor centerline such that the rolls, in combination, define a chevron pattern around the wrapping angle,
- wherein the strip material is continuously centered on the conveyor around the wrapping angle by the action of the rolls when the conveyor transports the strip material.
A quadrant roll conveyor for conveying strip material around a quadrant roll of any desired wrapping angle, comprising:
- three substantially parallel support members, with one of the support members positioned coaxial with a conveyor centerline;
- and
- a plurality of rolls, wherein each of the rolls is journaled for rotation in two of the three support members,
- wherein the rolls are arranged in a plurality of roll pairs, with the respective rolls in the roll pairs positioned on opposite sides of the conveyor centerline,
- wherein the rolls in the roll pairs have a separate, straight shafts positioned at an angle of less than 90° with the conveyor centerline such that the rolls, in combination, define a chevron pattern around the wrapping angle,
- wherein the strip material is continuously centered on the conveyor around the wrapping angle by the rolls when the conveyor transports the strip material, and
- wherein the shafts of the rolls in the roll pairs have an axis of rotation intersecting the axis of rotation of the corresponding shaft located on the opposite side of the conveyor centerline at a point in a vertical plane passing through the conveyor centerline.
A method of using a quadrant roll conveyor to convey strip material around a quadrant roll of any desired wrapping angle, comprising the steps of:
- providing the quadrant roll conveyor, with the conveyor further comprising:
- three substantially parallel support members, with one of the support members positioned coaxial with a conveyor centerline;
- and
- a plurality of at least partially crowned rolls, wherein each of the rolls is journaled in two of the three support members, wherein the rolls are arranged in a plurality of roll pairs, with the respective rolls in the roll pairs positioned on opposite sides of the conveyor centerline, and wherein the rolls in the roll pairs have separate, straight shafts positioned at an angle of less than 90° with the conveyor centerline such that the rolls, in combination, define a chevron pattern around the wrapping angle;
- positioning the strip material on the conveyor;
- tensioning the strip material such that the strip material moves in a conveying direction around the quadrant roll defined by the conveyor;
- and
- continuously centering the strip material on the conveyor around the wrapping angle with the rolls.
