Abstract

249,141. Vereinigte Glanzstoff-Fabriken Akt.-Ges. March 12, 1925, [Convention date]. Apparatus for making filaments.- In the dryspinning of artificial threads, the filaments are spun downwardly into an unheated atmosphere, that is, the spinning cell is not heated, while a current of air passes through the cell in the same direction as the filaments; the freshlyspun thread is subsequently passed into a heated cell in order to free it from residual solvent. By the heating the threads are caused to assume a glossy appearance. As shown, the filaments are spun downwardly in a cell 1, normally pass to a guide 4, and leave the cell through an opening 5; through the cell passes a current of air entering at openings 7 near the spinning-nozzle 3, travelling with the threads, and leaving through the exhaust pipe 8. The heating-chamber 2 is arranged adjacent to the spinning-cell 1, being provided with a winding-device 16, heating devices 15, air inlets 13, and exhaust piping 14. The cell and chamber are fitted with doors 9 - - 12. At starting the filaments are collected at a guide 4<1>. Instead of the heating-chamber shown, the threads either freely or upon a carrier, may be passed through a heating-cell, and subsequently reeled upon a device located outside the cell. The Specification as open to inspection under Sect. 91 (3) (a) includes broadly the employment of an unheated spinning cell and heating the threads after leaving the spinning cell. This subject-matter does not appear in the Specification as accepted. Specification 236,393 is referred to.
