Embodiment Construction

[0016] 1 and 2 partially show a drafting mechanism, in particular a load arm 1 of a drafting mechanism for a ring spinning machine. The load arm 1 has a U-shaped profile 2 . The load arm is supported at its not-shown end on a support rod parallel to the lower rollers of the drafting mechanism, one of which is shown here as the lower roller 9 . The load arm 1 is guided on a support rod and is rigidly constructed such that it can pivot in a plane perpendicular to the lower roller 9 . The load arm 1 supports a plurality of upper rollers in the form of double pressure rollers 6 , of which only one double pressure roller 6 is shown, and which are allocated in corresponding numbers to the lower rollers. The double pressure roll 6 comprises two roller core top rollers which are supported on a common roller shaft 7 and which is clamped between these two roller core top rollers. The fiber strands 10 run between each upper and lower roll 9 of the double pressure rollers 6, and the fib...

Abstract

The invention relates to a pressure roller support for fixing double pressure rollers in a drafting mechanism, which comprises a spring for pressing the double pressure rollers and a fixing frame for the double pressure roller shafts. The holder is a die-cast or injection-molded part, wherein the holder is cast onto the spring. Furthermore, the invention relates to a method for producing the pressure roller support, in which the spring is inserted into the mold at least in a partial region so that the holder is connected to the spring during the casting process.

Description

technical field [0001] The present invention relates to a pressure roller support for fixing the double pressure rollers in the drafting mechanism, which comprises a spring for pressing the double pressure rollers and a fixing frame for fixing the roller shafts of the double pressure rollers, wherein the The holder is cast as a die-cast or injection-molded part. [0002] Furthermore, the invention relates to a method for producing a roller support for fixing the double pressure rollers in the drafting mechanism, wherein a spring pressing the double pressure rollers is associated with a fixing frame for the roller shafts of the double pressure rollers. connected, and wherein the holder is cast in a mold as a die-cast or injection-molded part.
