Post machines with top and button wheel  feed are mainly used for manufacture shoe  uppers around the world. When process ing heavy materials (e.g. winter shoes,  military shoes, work shoes) the machines  quickly reach their limits. For such “heavy  applications”, the German Sewing machine  company PFAFF recommend to use special  heavy duty machines of the series 1243/44  and 1293/94, which can process a thread  size of up to 8/3 syn. (needle sizes Nm 160  to 200).

The machines are equipped with  drop feed and retractable roller presser  with direct drive. The roller presser drive  guarantees problem-free top-stitching of seam intersections without any change  of stitch length (subclass -4/01). The  machines ensure a very good seam quality  when sewing rope-stitch, ornamental and  assembly seams – due to toothed belt drive a  proven, strong power transmission is guaranteed. A constant stitch length, even when  sewing over thick spots, can be managed  with that solid PFAFF series. All machines  can be optionally equipped with automatic  thread trimmer and automatic backtacking  mechanism with additional quick button on  machine head for backtrack inside seams and  automatic roller presser lifter. The clearance  under the roller presser is 7 mm.
