Abstract
A machine for closing an open end of a cover encasing a mattress core in order to form a mattress is provided. A frame is adapted to support at least an edge portion of the mattress core encased in the cover. A mattress core press is mounted on the frame for vertical movement and is adapted to compress an edge of the mattress core to a desired height. A mattress cover clamp is mounted on the frame for vertical movement and is adapted to clamp free edges of the open end of the mattress cover together. A sewing head carriage is mounted on the frame for horizontal movement. A sewing head is mounted on the carriage, and a sewing head motor is mounted on the carriage for driving the sewing head. The sewing head is adapted to stitch the free edges of the open end of the mattress cover closed as the sewing head carriage traverses from one side of the mattress to the other side of the mattress.
