The yarn end finding apparatus includes an air current generating member and an air current control member for controlling an air current generated by the air current generating member in such a manner that the air current flows along the surface of yarn layers of a bobbin. The air current control member is disposed in a position either partially or totally surrounding the bobbin in order for the air current control member to be movable upward and with respect to the bobbin. The yarn end finding apparatus of the present invention is compact in structure so as to permit a yarn finding operation to be performed in a single location.

Yarn end finding apparatus and method

A system in which a plurality of spinning frames and a plurality of winders are connected by a common bobbin conveying passage, a circulating passage having a bobbin sensor is provided on a spinning bobbin supplying passage from the bobbin conveying passage to the winders, and a stopper is provided at an inlet of the circulating passage, the stopper being adapted to stop receiving bobbins when the number of passing bobbins per a predetermined time detected by the bobbin sensor exceeds a set value.

Bobbin supplying system

Bobbin supplying system having a bobbin reserve line

A tray conveyor apparatus for conveying a bobbin loaded on a tray while tilting the axis of the tray from a vertical position to a horizontal position and vice versa, having a first guide for guiding the neck of the tray off a support body which supports the bottom face of the base of the tray near a tilting point and a second guide for guiding the base of the tray between the first guide and the support body. The bobbin being carried on the conveyor of the aforesaid constitution is tilted by a curved guide while being guided at the base of the peg tray and at the neck supporting the bobbin and being supported by the support body. On the underground runway, therefore, the bobbin travels in the horizontal state.
