Cooling means for ringless spinning frame

摘要

A ringless spinning frame comprises a spinning frame body, above which a plurality of sliver cans are disposed on a platform, and a plurality of spinning units attached to the spinning frame body. A sliver from each sliver can is guided by a sliver guide conduit, which is disposed between the corresponding sliver can and spinning unit, to the corresponding spinning unit. The sliver guide conduits extend downwardly behind the corresponding spinning units and within the spinning frame body the interior of which reaches a temperature higher than that of the exterior by about 10 DEG to 20 DEG Celsius. To prevent the sliver guide conduits within the spinning frame body from being raised in temperature, the ringless spinning frame is provided with a device disposed near the sliver guide conduits for preventing heat produced in the spinning frame body from being transmitted to the sliver guide conduits.
