Abstract
Abstract Wire coming hot from a rolling mill is carried to a coil stacker on an apertured conveyor on which it cools after being deposited thereon in a series of overlapping loops by a dispenser including a continuously rotating tubular arm which is centered on a horizontal axis. A cutter ahead of the dispenser, responsive to a delayed trigger pulse from a photocell which monitors the entry of the leading end of the wire into an observation zone, removes the irregularly formed leading portion of any fresh length of wire but is inhibited from operating at instants when the arm is so oriented that the tip of the trimmed wire would reach its exit end in a position in which the wire tip could become entangled in the mesh with a grid-type conveyor or fall between parallel conveyor bands. This inhibition is brought about by a signal generator, such as an inductance co-operating with a magnet carried by the rotating arm, whose output either enables the cutter drive in a predetermined arm position or blocks it during the passage of the arm over certain parts of its orbit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
207 words
An apparatus for winding hot wire into a coil, comprising: an apertured conveyor; a rotary dispenser above said conveyor for depositing a continuous length of wire thereon in a succession of loops to be cooled preparatorily to stacking; a coil stacker positioned beyond said conveyor for receiving the cooled loops; monitoring means disposed ahead of said dispenser for generating a trigger pulse upon detecting the arrival of the leading end of a fresh length of wire fed at a predetermined rate to said dispenser; cutter means downstream of said monitoring means in the path of said length of wire for severing a predetermined leading portion therefrom; control meanS for said cutter means responsive to said trigger pulse, said monitoring means being provided with a timing circuit including delay means for retarding the arrival of said trigger pulse at said control means by a predetermined period corresponding to the length of the leading portion to be severed; and signaling means at said dispenser having an output circuit connected to said control means for synchronizing the operation of said cutter means in response to said trigger pulse with the rotation of said dispenser to prevent the emergence of the foreshortened wire from the dispenser in an unfavorable angular position.
Claim 2
Independent Claim
207 words
An apparatus for winding hot wire into a coil, comprising: an apertured conveyor; a rotary dispenser above said conveyor for depositing a continuous length of wire thereon in a succession of loops to be cooled preparatorily to stacking; a coil stacker positioned beyond said conveyor for receiving the cooled loops; monitoring means disposed ahead of said dispenser for generating a trigger pulse upon detecting the arrival of the leading end of a fresh length of wire fed at a predetermined rate to said dispenser; cutter means downstream of said monitoring means in the path of said length of wire for severing a predetermined leading portion therefrom; control meanS for said cutter means responsive to said trigger pulse, said monitoring means being provided with a timing circuit including delay means for retarding the arrival of said trigger pulse at said control means by a predetermined period corresponding to the length of the leading portion to be severed; and signaling means at said dispenser having an output circuit connected to said control means for synchronizing the operation of said cutter means in response to said trigger pulse with the rotation of said dispenser to prevent the emergence of the foreshortened wire from the dispenser in an unfavorable angular position.
Claim 3
Dependent Claim
36 words
An apparatus as defined in claim 1 wherein said dispenser comprises a bent guide tube with an entrance end centered on a substantially horizontal axis of rotation and an exit end generally transverse to said axis.
Claim 4
Dependent Claim
22 words
An apparatus as defined in claim 2 wherein said signaling means comprises a generator of timing pulses operatively coupled with said tube.
Claim 5
Dependent Claim
31 words
An apparatus as defined in claim 3 wherein said generator includes magnetic means on said tube and a pick-up coil adjacent said tube positioned for periodic excitation be said magnetic means.
Claim 6
Dependent Claim
34 words
An apparatus as defined in claim 1 wherein said timing circuit includes pulse-shaping means for broadening the delayed trigger pulse to at least a substantial fraction of a cycle of rotation of said dispenser.
Claim 7
Dependent Claim
43 words
An apparatus as defined in claim 5 wherein said signaling means has an output in the form of a recurrent enabling pulse, said pulse-shaping means broadening the delayed trigger pulse to a width at least equaling the recurrence period of said enabling pulse.
Claim 8
Dependent Claim
39 words
An apparatus as defined in claim 5 wherein said signaling means has an output in the form of a blocking pulse, said pulse-shaping means broadening the delayed trigger pulse to a width greater than that of said blocking pulse.
Claim 9
Dependent Claim
25 words
An apparatus as defined in claim 7 wherein the width of said blocking pulse corresponds to at least a quarter of said cycle of rotation.
