Drawing equipment for a knitting machine

Abstract

Drawing equipment for a knitting machine for the production of a fiber material from a roving includes double belts, guided via a pair of belt rollers and a pair of output pressure rollers. The pair of belt rollers and the pair of output pressure rollers respectively have an upper roller and a lower roller, which is driven by an electric motor. All of the drawing equipment rollers are disposed on the front-side of a base plate. Axles of the rollers are guided through the base plate. Drive means for the lower rollers of any roller pair are disposed at least partially on the rear-side of the base plate. Disposed on the upper roller of the pair of output pressure rollers and on the upper roller of the pair of belt rollers is suction equipment which extends over both of the upper rollers.

1 . Drawing equipment for a knitting machine for the production of a fiber material from a roving, comprising:
 double belts;   a pair of belt rollers; and   a pair of output pressure rollers;   wherein the double belts are guided by the pair of belt rollers and the pair of output pressure rollers;   wherein the pair of belt rollers and the pair of output pressure rollers respectively have an upper roller and a lower roller, which is driven by an electric motor;   wherein all of the rollers are disposed on a front-side of a base plate, whilst axles thereof are guided through the base plate;   wherein drive means for the lower rollers are disposed at least partially on a rear-side of the base plate; and   wherein on the upper roller of the pair of output pressure rollers and on the upper roller of the pair of belt rollers, suction equipment is disposed which extends over both of the upper rollers.   
     
     
         2 . The drawing equipment according to  claim 1 , further comprising a pair of input pressure rollers. 
     
     
         3 . The drawing equipment according to  claim 1 , wherein the suction equipment at least covers the upper output roller of the pair of output pressure rollers at least partially at a free end thereof. 
     
     
         4 . The drawing equipment according to  claim 1 , wherein a rear-side of the base plate is covered at least partially in an air-impermeable manner by a housing cover provided with at least one supply opening for compressed air, and wherein the base plate has through-openings for the compressed air. 
     
     
         5 . The drawing equipment according to  claim 4 , wherein the through-openings are formed by axial holes for the axles of the upper rollers, through which upper roller axles of the roller pairs are guided with clearance. 
     
     
         6 . The drawing equipment according to  claim 1 , further comprising at least one nozzle for receiving the drawn fiber material is disposed after the pair of output rollers. 
     
     
         7 . The drawing equipment according to  claim 6 , wherein the suction equipment suctions off the fiber material upon blockage of the at least one nozzle. 
     
     
         8 . The drawing equipment according to  claim 1 , wherein a front-side of the base plate is covered at least in regions with a housing cover.
