Abstract
A device and a method wind a thread on a winding machine. The winding machine has a spool sleeve and a spool holder, which has two oppositely disposed centering plates, having an adjustable axial distance relative to each other, for tensioning the spool sleeve. The centering plates each have a centering cone which engages in an open spool sleeve end, and an arrester hook for arresting the thread being provided in one of the centering plates. The arrester hook is oriented in the circumferential direction of the centering plate, and the centering plate having the arrester hook contains an outer cone which overlaps the outer diameter of the spool sleeve end. An inside of the arrester hook is formed by a nose-like recess provided in the outer cone.
Claims10
A device for winding a thread on a winding machine, the device comprising:
- at least one bobbin tube having open bobbin tube ends formed therein, an outer side and an end face;
- and
- a bobbin holder having two opposing centering disks, adjustable in their axial distance from one another, for tensioning said at least one bobbin tube, wherein said centering disks each having a centering cone engaging in one of said open bobbin tube ends, wherein, on one of said centering disks, a fixed hook for catching the thread, being aligned in a circumferential direction of said one centering disk being formed, said one centering disk containing said fixed hook having an outer cone overlapping an outer diameter of a bobbin tube end of said bobbin tube ends, said fixed hook having an inner side with a nose-shaped recess formed therein and disposed at least in said outer cone, and when said at least one bobbin tube is clamped to the device an edge is applied between said outer side and said end face of said at least one bobbin tube end on an inner wall of said outer cone.
A method for winding a thread on a winding machine onto a bobbin tube being tensioned by two opposing centering disks of a bobbin holder that are adjustable in their axial distance from one another, the centering disks each having a centering cone engaging in an open bobbin tube end of the bobbin tube, which comprises the steps of:
- catching the thread with a fixed hook disposed on one of the centering disks and aligned in a circumferential direction of the one centering disk, the one centering disk containing the fixed hook having an outer cone overlapping an outer diameter of the bobbin tube end, and that the thread, when the bobbin tube rotates, slides into a nose-shaped recess provided at least in the outer cone, forming an inner side of the fixed hook, and the thread being clamped at a thread clamping point formed between an inner wall of the outer cone and an edge between an outer side and an end face of the bobbin tube end.
