Abstract
Apparatus including a mattress support for supporting a mattress lying on a first major face or panel thereof and conveying the mattress as a sewing operation, such as an edge sewing and taping operation, is performed with respect to the first major face. A mattress flipping mechanism is provided and may include a pivoting support portion of the mattress support connected to a powered lift mechanism. In one preferred embodiment the mattress support includes a split conveyor and the pivoting support portion of the mattress support is disposed within the space defined between adjacent belts of the split conveyor. Mattress elevating units are provided to create slack in the top panel of the mattress for easier grasping by the operator during a sewing operation. A mattress guide arm is provided for holding the mattress down during the sewing operation. A sewing machine base is pivoted and connected to a fluid powered cylinder for moving the sewing machine away from the mattress support while flipping the mattress. The mattress guide arm is provided with pivoting features for this reason as well.
