ABSTRACT:
A thread seeking apparatus for handling thread wound on a core of a cop has a cop holding arrangement rotatable about a vertical axis. Also included is an axially symmetrical housing chamber for containing the cop. The housing chamber is sized to have an annular space remaining between the outside of the cop and the inside of the housing chamber. The housing chamber includes a pair of half-shells laterally reciprocatable between an open position and a closed seeking position. The apparatus includes a streaming channel that can receive the thread taken from the circumference of the cop. The streaming channel is positioned to communicate with the upper end of the housing chamber. An inlet jet is mounted at one end of the housing chamber for communicating with the annular space in the housing chamber and causing an airflow therein. Also included is a headpiece connected with the streaming channel and bordering the housing chamber. The headpiece has a bell-shaped mouth for embracing the upper end of the cop. The headpiece is reciprocatable between an engaged and disengaged position while the half-shells are in the closed seeking position.
