911,098. Drafting-apparatus. SKF. KUGELLAGERFABRIKEN G.m.b.H. Dec. 16, 1960 [Dec. 17, 1959 ; Oct. 20, 1960], No. 43356/60. Class 120 (2). In double-apron drafting-mechanism where a bridge-guide for the lower apron is at least adjustable transversely of the drafting-field and is detachably connected by a fixing member, e.g. a screw 14, to a fixed part of the machine, the guide 10, Fig. 2, is rigid and is located relatively to the fixed part 1, e.g. the bearing- bracket in which the lower rolls are mounted, through positioning members 16, Fig. 3, which can be exchanged to vary the position of the guide and which are secured by the screw &c. 14 which connects the guide to the fixed part 1. As indicated in Fig. 2, a lower apron 11 and a guide 10 are arranged on either side of bracket 1 ; one set of members 16 serves both guides at each bracket and each member 16 is slotted to receive a screw 14. Each guide has downturned parts 10<SP>1</SP>, Fig. 3, which engage the sides of a recess either in the bracket or a member secured to it by the screw 14, and inclined parts 10<SP>11</SP> to guide the apron. A block 15 may be provided between the guide and the members 16 and one or other of these parts may be magnetized to hold them together when they are removed. In an alternative form, Fig. 4, the bracket has ribs 19, co-operating with the members 16 which take the form of curved strips 16<SP>1</SP> which may be such as to permit the guide to be canted. To enable the position of the guide to be adjusted e.g. along the line of draft, the screw 14 may extend through a slot either in the guide or the holder above referred to; in the former case, the ends 10 do not extend as far as the sides of the recess in the bracket and the guide and the block may have co-operating ridges, Fig. 8. To permit the guide to be accurately positioned, markings may be provided on the bearing bracket 1, or on the locating means in Fig. 8.
