US 5,799,374 A · Spinning machine for the doubling or stretching of fiber bands

Abstract

A spinning machine for the doubling or stretching of fiber bands with a rolling section having lower rolls which are secured in journal blocks, and wherein the upper rolls may be also secured on said journal blocks with pressure means for the loading of said upper rolls, it is proposed that the pivoting axis of the pressure arm for the placement of the pressure means to the upper rolls be arranged in such a way that, when observed in the running direction of the fiber band, said axis lies behind the rolling section. Advantageously, what is achieved thereby, is that the spinning machine can be maintained in a considerably simpler and quicker manner. Following the upward pivoting of the pressure arm, the entire area of the rolling section becomes freely accessible. The pivoting geometry of the pressure arm can be so varied, that the upper rolls can be easily restored into the guides on the journal blocks of the lower rolls.

Dependent claims

A textile spinning machine for doubling or stretching fiber bands, comprising:

a rolling section having pairs of upper and lower rolls, said lower rolls held in journal blocks, wherein said fiber band is conveyed between said upper and lower rolls in a conveying direction, said pairs of rolls including an entering pair of rolls and an exit pair of rolls in said conveying direction;
pressure mechanisms disposed to load said upper rolls toward said lower rolls;
a pivotally mounted pressure arm, said pressure mechanisms mounted on said pressure arm, said pressure arm pivotable between a closed position wherein said pressure mechanisms load said upper rolls against said lower rollers, and an open position wherein said upper rolls are unloaded relative to said lower rolls;
and
a pivot axis for said pressure arm which is disposed behind said rolling section in said conveying direction and below a horizontal plane through a rotational axis of said lower roll of said exit rolls.
