Apparatus for the manufacture of mattress plates

1. An apparatus for the production of at least approximately rectangular mattress plates from a length of material which is continuously fed to the apparatus, the apparatus including a base frame with a transport path for the length of material, a feed drive for feeding the length of material in a transport direction (A), two lateral sewing stations which are arranged at an adjustable distance from each other on a crossbeam of the base frame directed transversely across the transport path and which are each provided with a longitudinal sewing head for producing a lateral seam and with a longitudinal cutter, a transverse sewing station which is arranged on a crossbeam of the base frame directed transversely with regard to the transport direction (A) across the width of the transport path such that the transverse sewing station can be moved along said crossbeam and which is provided with a transverse sewing head as well as a transverse cutter, a transverse drive for moving the transverse sewing station, and a control device for controlling the feed drive, the transverse drive, the lateral sewing stations, and the transverse sewing station, wherein the lateral sewing stations are each pivotable by means of a rotary drive about an axis extending perpendicularly with regard to the plane of the transport path and moveable along their crossbeams by means of a translatory drive and in that the translatory drive and the rotary drive are controllable by means of the control device in coordination with the feed drive for the length of material.

2. The apparatus according to claim 1 , wherein the sewing heads of the lateral sewing stations are designed as two-needle machines for producing a double seam, and the corresponding longitudinal cutters are designed for producing a cut along a cutting path, each said longitudinal cutter being arranged such that the cutting path runs to one side of the double seam produced by the respective lateral sewing station.

3. The apparatus according to claim 1 , wherein the sewing head of the transverse sewing station is designed as a four-needle machine for producing two parallel double seams, and the transverse cutter is designed for producing a cut along a cutting path, said transverse cutter being arranged such that the cutting path runs between the two double seams produced by the transverse sewing station.
