Definitions

  • the present invention has reference to an improved apparatus for squeezing out liquids from webor sheetlike textile materials incorporating four rollers having their axes substantially in parallelism, of which two drivable rollers are stationary and two rollers serving as pressure or squeezing rollers are displaceably arranged.

Supports can be arranged beneath the rollers which are configured in accordance with the arrangement of the rollers. Additionally, in the region of the supports and at other locations there are mounted deflecting rollers for the textile material.
  • the present invention is directed to an improved apparatus for squeezing liquid from web-shaped textile materials and contemplates constructing the apparatus such that the roller arrangement can be accomrnodated to almost all operating conditions and is suitable for each type of dyeing and each finishing liquid, so that no compromise is necessary, on the one hand, between the roller arrangement most favorable for the dye and the fabric, and, on the other hand, the arrangement possible with the existing machine.
  • the physical structure of inventive apparatus which enables this objective to be achieved is characterized by the feature that two rollers are vertically arranged above both of the other rollers.
  • the inventive apparatus for squeezing out liquids from web-shaped textile materials or the like comprises four rollers arranged with their axes substantially in parallelism with one another, two of these rollers are drivable and fixedly mounted, and means are provided for mounting the other two of said rollers defining squeezing rollers so as to be displaceable.
