Yarn feed-separation device

摘要

A device to enable yarn to be fed for textile applications and the relative turns to be separated. The device includes a wheel/drum directly or indirectly motorized for rotation about its axis, the wheel/drum presenting in its lateral surface a series of slits to receive relative blades the projecting profile of which enables the yarn turns wound on the wheel/drum to advance. The blades form an assembly which rotates together with the wheel/drum but about an axis having an inclination and/or an eccentricity relative to the axis of the wheel/drum, such that the profile projection of the blades from the relative slits varies gradually along the perimeter of the wheel/drum, from a minimum to a maximum, to then return to a minimum, but remains constant with time. The blades have a length to be able to receive all the yarn turns which concern the device.

1. A device for feeding yarn for textile applications, and for separating the relative turns, comprising:
a wheel/drum directly or indirectly motorized for rotation about an axis of the wheel/drum, the wheel/drum presenting in a lateral surface of the wheel/drum a series of slits to receive relative blades a projecting profile of the blades enables the yarn turns wound on the wheel/drum to advance, the blades forming an assembly which rotates together with the wheel/drum but about an axis of the blade having an inclination angle (α) and/or an eccentricity (e) relative to the axis of the wheel/drum, such that the profile projection of the blades from the relative slits varies gradually along the perimeter of the wheel/drum, from a minimum to a maximum, to then gradually return to a minimum, but remains constant with time for simultaneously rotating the wheel/drum about the wheel/drum axis and rotating the blades about the axis of the blade, the blades having a length to receive all the yarn turns which concern the device, means for adjusting inclination of the axis of the blade assembly to the axis of the wheel/drum; and/or for adjusting the eccentricity of the axis of the blade to the axis of the wheel/drum, to consequently adjust the extent of separation between the yarn turns wound on the wheel/drum.
