Abstract
A material feeding device includes material wrapped around a spool, the spool rotating around an axis. A material feeding mechanism feeds the material in a feeding direction, thereby unraveling the material from the spool. A force deflection device is arranged between the spool and the material feeding mechanism, and is connected to the material. The force deflection device is configured to as to deform physically when the material feeding mechanism applies an initial feeding force to the material.
Claims8
A material feeding device comprising:
- a spool configured so as to rotate around an axis;
- a material which is wrapped around the spool;
- a material feeding mechanism which is configured to feed the material in a feeding direction, thereby unraveling the material from the spool;
- and
- a force deflection device which is arranged between the spool and the material feeding mechanism, and is connected to the material;
- wherein the force deflection device is configured to as to deform physically when the material feeding mechanism applies an initial feeding force to the material.

A method of feeding a material from a spool, the method comprising:
- providing a spool which rotates around an axis;
- providing a material which is wrapped around the spool;
- applying an initial feeding force to the material so as to unravel the material from the spool;
- and
- physically deforming a force deflection device which is connected to the material and absorbs a portion of the initial feeding force before the initial feeding force is transferred to the thread on the spool.
