Apparatus and method for supplying tire material members

An apparatus for supplying tire material members, the apparatus comprising:

• a feeder that feeds out a first continuous material member from which a first material member is to be cut out and a second continuous material member from which a second material member is to be cut out;
• a conveyer that conveys the first continuous material member and the second continuous material member;
• a cutter that cuts the first continuous material member and the second continuous material member at a cutting position along a crossing direction perpendicular to a conveyance direction of the first continuous material member and the second continuous material member every time when the first continuous material member and the second continuous material member are conveyed by a predetermined length;
• a position detector that, prior to cutting by the cutter, detects positions of the first continuous material member and the second continuous material member along the conveyance direction while the first continuous material member and the second continuous material member are conveyed by the predetermined length from the cutting position;
• a position adjuster that includes a controller that compares a length of the first continuous material member along the conveyance direction with, a length of the second continuous material member along the conveyance direction based on a detection result of the positions of the first continuous material member and the second continuous material member by the position detector while the first continuous material member and the second continuous material member are conveyed by the predetermined length from the cutting position, and prior to cutting by the cutter, controls the conveyer to make downstream ends of the first continuous material member and the second continuous material member identical to each other along the conveyance direction based on a comparison result of the lengths of the first continuous material member and the second continuous material member along the conveyance direction;
• and
• a supplemental position detector that is located downstream from the position detector along the conveyance direction, and detects downstream ends of the first material member cut out from the first continuous material member by the cutter and the second material member cut out from the second continuous material member by the cutter,
• wherein the feeder is adapted to feed out the first continuous material member and the second continuous material member in parallel with each other with a gap between the first continuous material member and the second continuous material member in the crossing direction perpendicular to the conveyance direction such that the first continuous material member and the second continuous material member are not in contact with each other, and
• wherein the position detector also detects upstream ends of the first material member and the second material member when the supplemental position detector detects the downstream ends of the first material member and the second material member.
