Abstract
An apparatus for holding tubular goods for stitching at the station of a sewing machine has a support adjacent the sewing station, a drive for rotating the support about a horizontal support axis, and at least three arcuate segment plates displaceable radially of the support axis on the support and together forming a segmented drum centered on the axis. The plates are displaceable between inner positions defining a circumference smaller than that of the smallest tubular goods to be sewn and outer positions defining a circumference larger than that of the largest tubular goods to be sewn. The plates can be radially spread on the support to change the diameter of the drum. Thus when a tubular workpiece is fitted over the drum it is tensioned thereover. The support can also be displaced vertically adjacent the station to align the uppermost segment plate generally with the stitch plate. The support is a disk formed with respective radial guides and the plates have radially extending elements received in the respective guides. The radial elements have radially outer ends pivoted on the respective plates and radially inner ends.
