Abstract
Abstract A device for depositing and keeping a thread end in a cop tube of a spinning cop from a cop delivery point of a cop preparation station to a cop transporting device includes a pivotable chute with upper and lower ends disposed between the cop delivery point and the cop transporting device for receiving a spinning cop with a dragged-along thread end, a switchable suction device disposed at the lower end of the chute for supplying the cop tube with suction, and a device for tilting the chute from a vertical position to a horizontal position, the tilting device including a device for limiting acceleration and deceleration of the spinning cop in the chute during tilting.

Device for depositing and keeping a thread end in a cop tube of a spinning cop from a cop delivery point of a cop preparation station to cop transporting means, comprising a pivotable chute with upper and lower ends disposed between the cop delivery point and the cop transporting means for receiving a spinning cop with a dragged-along thread end, a switchable suction device disposed at said lower end of said chute for supplying the cop tube with suction, and a device for tilting said chute from a vertical position to a horizontal position, said tilting device including means for limiting acceleration and deceleration of the spinning cop in said chute during tilting.
Claim 3
Dependent Claim
14 words
Device according to claim 1, wherein said suction device includes a controlled thread cutter.
Claim 4
Dependent Claim
19 words
Device according to claim 1, including a cop retainer disposed at the delivery point being controlled by said chute.
Claim 5
Dependent Claim
47 words
Device according to claim 3, wherein said cop retainer is a swing being moved with said chute when said chute is pivoted into the vertical position, being pivotable laterally, and being released when said chute is pivoted into the horizontal position, and said delivery point being closeable.
Claim 6
Dependent Claim
54 words
Device according to claim 3, including a cop shunting switch disposed downstream of said chute in cop travel direction, a thread-presence feeler being disposed above said cop retainer and being activated with a delay when a retained cop is released, and a functional connection connected between said thread-presence feeler and said cop shunting switch.
Claim 7
Dependent Claim
49 words
Device according to claim 5, wherein said thread-presence feeler is also a cop-presence feeler issuing a cop-presence signal, and said thread and cop-presence feeler includes a switching delay device switching from cop measurement to thread measurement after said cop-presence signal stops and after a given time delay has expired.
Claim 8
Dependent Claim
36 words
Device according to claim 1, including a horizontal conveyer disposed between said chute and the transporting means, said horizontal conveyer including means for limiting acceleration and deceleration of a spinning cop disposed on said horizontal conveyer.
Claim 9
Dependent Claim
29 words
Device according to claim 1, wherein said means for limiting acceleration and deceleration of a spinning cop disposed in said chute are in the form of a crank drive.
Claim 10
Dependent Claim
30 words
Device according to claim 7, wherein said means for limiting acceleration and deceleration of a spinning cop disposed on said horizontal conveyer are in the form of a crank drive.
Claim 11
Dependent Claim
