Abstract
An open-end rotor spinning machine includes open-end spinning apparatuses each having a rotor housing, a spinning rotor revolving at high rpm in the rotor housing, and a yarn draw-off device extending into the spinning rotor. A cooling device includes a channel plate closing the rotor housing in an operating state. The channel plate has double walls defining a cooling chamber therebetween surrounding the yarn draw-off device. Connection sleeves connect the cooling chamber to a coolant loop.
Claims8
An open-end spinning apparatus, comprising a rotor housing, a spinning rotor revolving at high revolutions in the rotor housing, and a yarn draw-off device extending into the spinning rotor, and a cooling device for cooling said yarn draw-off device, said cooling device including
- a channel plate for covering the rotor housing in an operating state, said channel plate having double walls defining a cooling chamber therebetween surrounding said yarn draw-off device, and a coolant loop communicating with said cooling chamber.
An open-end rotor spinning machine comprising individual open-end spinning apparatuses and a common coolant loop, each of said spinning apparatuses having a rotor housing, a spinning rotor revolving at high revolutions in said rotor housing, and a yarn draw-off device extending into said spinning rotor, and a cooling device connected in said common coolant loop, said cooling device including
- channel plates each for covering a respective one of said rotor housings in an operating state, said channel plates each having double walls defining a cooling chamber therebetween surrounding a respective one of said yarn draw-off devices.
