Abstract

780,365. Making filters; coiling; rolling. KNECHT, A. July 15, 1955 [Nov. 9, 1954], No. 20508/55. Classes 83 (2) and 83 (4). A method of winding wire on perforated externally, longitudinally ribbed cylindrical slot filter formers comprises passing circular section wire through forming rolls which give it a polygonal cross-section and feeding the formed wire through a guide member to a slot filter former held between the chuck and tailstock of a lathe and rotated to wind the wire thereon, the guide member extending from the rolls to the former. Circular-sectioned wire 12 from a reel 13 on a plate 10 attached to the slide rest of a lathe is passed through a felt cleaning swab 29, over a grooved guide pulley 27 and beneath wirelubricating means 33 to spring-loaded forming rolls 17, 18 also carried on the plate 10. The rolls are driven from a motor 22 through a clutch 24 and the roll 17 is smooth while the roll 18 is peripherally channelled so as to give the wire a triangular section, Fig. 1, or a trapezoidal section. From the rolls 17, 18 the formed wire 6 passes through a guide 30 to a slot filter former 1 held between a chuck 7 and tailstock pin 8 of the lathe. The former 1 is of cylindrical form with perforations 2 and external longitudinal ribs 4. The ribs 4 have indentations 5 which form a spiral groove for the reception of the formed wire 6.
