Abstract
Abstract Automatic winding machine for large-volume supply coils that are delivered by a transporting device to respective winding stations of the machine whereat respective means for unwinding the supply coils are located includes a coil loading carriage drivable past the winding stations. The coil loading carriage has both conveyor means for transferring supply coils from the transporting device to the coil unwinding means of the respective winding stations, as well as make-ready means for readying incompletely unwound supply coils to immediately continue the unwinding operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
114 words
In an automatic winding machine for large-volume supply coils having a plurality of winding stations, each of said stations having means for unwinding the supply coils, a transporting device located a distance away from said unwinding means and positioned relative to said winding stations to deliever said coils to respective winding stations of the machine, a coil loading carriage drivable past the unwinding means, said coil loading carriage comprising conveyor means movable alternatively into respective positions adjacent said unwinding means and said transporting device and transferring the coils to the coil unwinding means of the respective stations, said coil unwinding means having make-ready means for readying supply coils to immediately continue the unwinding operation.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
25 words
Automatic winding machine according to claim 1 wherein said conveyor means comprise a receiving member for directly receiving the supply coils from the transporting device.
Claim 4
Dependent Claim
15 words
Automatic winding machine according to claim 2 wherein said receiving member is a sliding trough.
Claim 5
Dependent Claim
34 words
Automatic winding machine according to claim 1 wherein said make-ready means has means for operating upon a supply coil located in a predetermined position in the coil unwinding means of the respective winding stations.
Claim 6
Dependent Claim
65 words
Automatic winding machine according to claim 1 wherein the coil unwinding means of the respective winding stations have means for holding in ejection position a supply coil that has been at least partially unwound by the coil unwinding means, said loading carriage having remainder sensing means for determining the winding condition of the supply coil in the ejection position of the respective coil unwinding means.
Claim 7
Dependent Claim
71 words
Automatic winding machine according to claim 1 wherein the coil unwinding means of the respective winding stations has means for holding in made-ready position a supply coil that is ready to be unwound by the coil unwinding means, said loading carriage having suction nozzle means for seeking the starting end of the thread carried by the supply coil that is located in the made-ready position of the respective coil unwinding means.
Claim 8
Dependent Claim
70 words
