COLD FORMING OF METALS guard is a solid metal plate covering the nip pomt lor the full length of the rolls Tins plate, equipped with a stud welded to each end, is attached to slotted vertical brackets by means of nuts and washers, so that it is adjustable vertically The bracket can be either welded or bolted to the feed table If desirable, the horizontal member of this bracket also can be slotted to give further adjustability The feed table may be made adjustable vertically by making the legs of pipe of dif ferent diameters to achieve a telescopic ef fect The larger, or base section, should be equipped with a setscrew of sufficient size to ensure stability when adjustment has been made Further stability is given this feed table by welding foot plates to the base section of the leg Another method of protection, although less desirable, consists of emergency tap ping bars connected to electric cutoff switches or, preferably, reverse electric switches Such emergency bars may be in stalled at knee level m front of the opera tor or directly m front of the bottom feed roll, far enough below the feed point to avoid accidental tapping Special-purpose feeding devices for nar row stock may be easily installed, as shown in Fig 23-46 References American Standards Association, 10 East 40th St, New York City Salety Code lor Power Presses Bll-1.
