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.
