Subalpine coniferous forests of central Honshu

What follows is a description of an improved apparatus for use in a spinning machine for the pickup of thread ends formed by thread breakage. The spinning machine includes at least one spinning station formed essentially of a rotatably mounted spindle and a spool mounted on the spindle. The spool has a thread wound thereon to form a bobbin. The apparatus associated with the spinning machine has a vacuum source, a suction mouthpiece connected to the vacuum source and positioned to lie opposite the bobbin and a drive for reversing the direction of rotation of the spindle after a thread breakage. The apparatus has been improved in order that the reverse rotation of the spindle is carried out at a sufficiently high rotational speed so that the rotational speed and the air stream resulting therefrom act on the thread end and effectively either cause or aid in causing the separation of the thread from the bobbin.
