Abstract An automatic spinning system has at least one spinning frame with opposite banks of spinning stations. A tractor carries a tender capable of randomly servicing the spinning stations. The tractor is mounted for back and forth movement between opposite ends of a track above the banks of spinning stations. The tender is mounted on the tractor for swinging movement about the ends of the spinning frame from one of the banks of spinning stations to the other bank when the tractor is at either of the opposite ends of its track. Thus, the tender patrols the stations as it travels in one direction along a continuous path about the banks of spinning stations, and is capable of randomly servicing the spinning stations. Either a broken strand of yarn or a full bobbin at a station requiring servicing is sensed by operating mechanism for stopping the tender in servicing orientation with the station requiring servicing, whereupon the tender doffs the bobbin from the station spindle and donns an empty bobbin and starts the strand winding onto the empty bobbin. Empty bobbins are conveyed to the tender and filled bobbins are conveyed from the tender as they are doffed. If desired, the tender may be equipped with a system for ridding the spinning frame of lint.

Total Claims: 4
Claim 1
Independent Claim
207 words
Strand processing apparatus for servicing strand processing stations of at least one strand processing machine having opposite banks of said strand processing stations, each station being arranged to process a strand comprising, means forming a continuous looped path along said opposite banks of said strand processing stations and completely about said machine, means for servicing said strand processing stations, a carrier mounting said servicing means for patrolling movement in said continuous looped path along one of said banks of said processing stations and then along the opposite bank of said strand processing stations, rectilinear track means positioned intermediate of and above said opposite banks of stations, said carrier being mounted on said track means, operating means for reciprocating said carrier between opposite ends of said rectilinear track means and for moving said servicing means along the entire length of said continuous looped path during said reciprocating movement of said carrier, said operating means including means for swinging said servicing means around opposing ends of said strand processing machine and for stopping said servicing means in servicing orientation with any station requiring servicing, and means for halting said reciprocating movement of said carrier at said opposite ends of the track means during said swinging of said servicing means.
Claim 2
Dependent Claim
207 words
Strand processing apparatus for servicing strand processing stations of at least one strand processing machine having opposite banks of said strand processing stations, each station being arranged to process a strand comprising, means forming a continuous looped path along said opposite banks of said strand processing stations and completely about said machine, means for servicing said strand processing stations, a carrier mounting said servicing means for patrolling movement in said continuous looped path along one of said banks of said processing stations and then along the opposite bank of said strand processing stations, rectilinear track means positioned intermediate of and above said opposite banks of stations, said carrier being mounted on said track means, operating means for reciprocating said carrier between opposite ends of said rectilinear track means and for moving said servicing means along the entire length of said continuous looped path during said reciprocating movement of said carrier, said operating means including means for swinging said servicing means around opposing ends of said strand processing machine and for stopping said servicing means in servicing orientation with any station requiring servicing, and means for halting said reciprocating movement of said carrier at said opposite ends of the track means during said swinging of said servicing means.
Claim 3
Dependent Claim
31 words
Apparatus as set forth in claim 1 in which said operating means temporarily stops said carrier with said servicing means in at least proximate servicing orientation with said station requiring servicing.
Claim 4
Dependent Claim
113 words
Apparatus as set forth in claim 2 including means for conveying empty bobbins to said servicing means and filled bobbins from said servicing means, and wherein said servicing means includes: means for receiving said empty bobbins from said conveying means and means for delivering filled bobbins to said conveying means, and means for doffing filled bobbins and for donning empty bobbins and starting said strand winding onto the donned bobbin at said station being serviced, and said operating means is responsive to the strand failing to be advanced at said station requiring servicing or to a full bobbin at said station requiring servicing to stop said servicing means at said station requiring servicing.
