Abstract
Method and apparatus are described by means of which the slitting head in a slitting line for severing sheet metal web material into strips is utilized to transfer the leading end of the web material from the uncoiler to the recoiler for attachment thereto during the feed-up operation. The invention enables the concerned operation to be performed more safely in reduced time and with less effort and manpower than heretofore.
Claims20
In a web slitting line including an uncoiler, a slitter head containing rotary slitting knives and a recoiler, a coil of web material carried by said uncoiler, said web material being adapted to extend through said slitter and be cut into strips, the method of feeding said web material from said uncoiler to said recoiler comprising the steps of:
- (a) moving said slitter head to a position closely adjacent said uncoiler;
- (b) unwinding said web material from said uncoiler to place the leading end thereof at the nip of said slitting knives;
- (c) engaging said web leading end by said slitting knives;
- (d) moving said slitter head to a position closely adjacent said recoiler;
- (e) operate said knives to move the leading end of said web into engagement with said recoiler;
- and
- (f) attaching said web leading end to said recoiler.
In a web slitting line containing an uncoiler, a coil of web material carried by said uncoiler, a recoiler spaced from said uncoiler, and a slitter head positioned intermediate said uncoiler and said recoiler and containing rotary slitting knives for slitting said web into multiple strips, the improvement comprising means for moving said slitter head from a position closely adjacent said uncoiler to a position closely adjacent said recoiler.
A slitter head adapted for movement between an uncoiler and a recoiler in a slitting line to mechanically feed-up the web being slit onto the recoiler mandrel comprising:
- (a) a frame;
- (b) opposed pairs of rotary knives mounted on said frame for slitting web material passed therebetween;
- (c) a pair of opposed pinch rolls on said frame forwardly adjacent said rotary knives adapted to drive said web material thereto;
- and
- (d) a peeling blade pivotally attached to said frame having a free end adapted to strip the outermost wrap of web material from said uncoiler when said frame is moved to a position adjacent thereto.
