Generally speaking, an automatic rewinding machine is constructed in such a way that one automatic rewinding machine is equipped with a large number of rewinding devices, and these rewinding devices are each equipped with a column magazine for holding a plurality of yarns. well known. On the other hand, various types of automatic pipe supply devices have been proposed and put into practical use for supplying the pipe threads to these magazine magazines. However, there are very few that are satisfactory in terms of handling and operation. On the other hand, the present applicant has invented and proposed various inventions and ideas regarding means for conveying the pipe yarn left by the spinning machine in the spinning process. The stub of the thread is pulled out and held through the top hole of the thread bobbin, and the stub holding thread is inserted into a tray into which the threads are individually inserted and conveyed. We have also proposed a device that has developed a yarn take-out device to extract and supply the conveyed tube yarn from the tray.

By the way, it is extremely convenient to load a single type of yarn into an automatic rewinding machine with a large number of rewinding devices arranged in a row, but special consideration is required when attempting to load different types of yarn. In particular, special measures are required to automatically feed different kinds of pipe yarns to the rewinding section where they are sorted into groups using the trays mentioned above. It is difficult to add more roads.
