Abstract
Abstract Strand handling apparatus including a system for controlling a cycling carriage which scans and services bobbin winding stations on a spinning machine, or the like. The control system provides a signal indicating when a station being scanned is operational and service signals indicating when the station requires servicing. Upon receipt of both the operational and servicing signals the control system initiates a work cycle of the carriage to service the station. The service signals include both a full bobbin signal and a strand interruption signal. If there are more than a predetermined number of interruption signals during a cycle, the control system does not cause servicing of the stations responsive to this signal. If a roll-wrap occurs on a drafting roll of a station the strand is broken and does not enter the drafting rolls and the operational signal is not provided at this station so that the carriage bypasses the station until it is again placed in operational condition by an attendant. Upon starting-up with fresh bobbins at all of the stations, most of the stations would be ready to have their full bobbins doffed at about the same time, and the carriage would be overworked. Therefore, at startup the control system provides for doffing the stations in succession at timed intervals, and in conjunction with the operational and the servicing signals, to randomize the future doffing cycle of the stations.

Claims Analysis
Total Claims: 21

Claim 2
Dependent Claim
117 words
For use with apparatus having a plurality of stations for winding packages or the like, a system for spacing at desired intervals servicing of the stations having full ones of the packages, the system comprising tending means actuable for servicing the stations in succession by doffing the package and starting winding of a new package at any of said stations during winding operation of the apparatus, and control means including first means for actuating the tending means in a timed succession to doff the packages and start winding of new paCkages, and second means operable concurrently with said first means for actuating the tending means to so service the stations independently of operation of said first means.
Claim 3
Dependent Claim
35 words
A system as set forth in claim 1 in which said control means further includes means for rendering said first means inoperative to actuate said tending means to twice so service any of said stations.

Dependent Claim
68 words
A system as set forth in claim 2 in which the rendering means includes indicator means, one for each of said stations, operable for indicating whether or not the station has been serviced by the tending means, and said first means is responsive only to said indicator means indicating that a station has not been so serviced for so actuating the tending means to so service the station.
Claim 5
Dependent Claim
167 words
For use with apparatus having a plurality of stations for winding packages or the like, a system for spacing at desired intervals servicing of the stations having full ones of the packages, the system comprising tending means actuable for servicing the stations in succession by doffing the package and starting winding of a new package at any of said stations during winding operation of the apparatus, and control means including first means for actuating the tending means in a timed succession to doff the packages and start winding of new packages, the first means includes timing means normally operable for so actuating the tending means in said timed succession, and in which the timing means is operable for measuring timed periods, means for operating said timing means to start measuring one of said periods each time the tending means is actuated to service a station, and means for effectively preventing successive operations of the tending means at the same station responsive to operation of the timing means.
Claim 6
Dependent Claim
167 words
For use with apparatus having a plurality of stations for winding packages or the like, a system for spacing at desired intervals servicing of the stations having full ones of the packages, the system comprising tending means actuable for servicing the stations in succession by doffing the package and starting winding of a new package at any of said stations during winding operation of the apparatus, and control means including first means for actuating the tending means in a timed succession to doff the packages and start winding of new packages, the first means includes timing means normally operable for so actuating the tending means in said timed succession, and in which the timing means is operable for measuring timed periods, means for operating said timing means to start measuring one of said periods each time the tending means is actuated to service a station, and means for effectively preventing successive operations of the tending means at the same station responsive to operation of the timing means.
Claim 7
Dependent Claim
39 words
A system as set forth in claim 4 in which the control means includes second means operable concurrently with said first means for actuating the tending means to so service the stations independently of operation of said first means.
Claim 8
Dependent Claim
35 words
A system as set forth in claim 5 in which said control means further includes means for rendering said first means inoperative to actuate said tending means to twice so service any of said stations.
Claim 9
Dependent Claim
68 words
A system as set forth in claim 6 in which the rendering means includes indicator means, one for each of said stations, operable for indicating whether or not the station has been serviced by the tending means, and said first means is responsive only to said indicator means indicating that a station has not been so serviced for so actuating the tending means to so service the station.
