Claims

[Scope of utility model registration request]

In a work trolley that is placed on a guide rail provided along with a plurality of rows of spinning units on a machine base and has a doffing device and a yarn splicing device, the work trolley communicates with a blower provided on the machine base and controls the movement direction of the work trolley. A slide duct is provided on the machine base in parallel with the main duct and is in pressure contact with a main duct having a suction opening corresponding to each unit, and is able to freely communicate with the hole of the main duct, and the slide duct is connected to the thread splicing device. A work trolley for a spinning machine, characterized in that it is equipped with a switching valve that arbitrarily switches between a duct communicating with a working member requiring suction pressure and a duct communicating with a working member requiring suction pressure in a doffing device. .
