Abstract
A method for continuous conditioning of a rubber blanket such as the type used on compressive shrinkage apparatus is described. The blanket includes an inner bearing surface defining a bearing face and an outer surface defining a web-contacting face. The web-contacting face is contacted under pressure with an abrasive conditioning roll while the blanket is in its regular, web treating operation. The blanket working face can thus be continuously conditioned without the need for lengthy machine stops. In this way, the conventional grinding and cleaning operations can be minimized or eliminated.
Claims29
A method for conditioning the web-contacting face of an endless rubber blanket on a compressive shrinkage apparatus comprising the step of
- contacting the surface of a rubber blanket with an abrasive roll while said blanket is in a web-treating motion, such that said abrasive roll removes a portion of the surface of the blanket as the blanket proceeds in its web-treating motion.
An apparatus for compressively shrinking a web of material comprising:
- an endless rubber blanket having a web contacting surface;
- means for supporting and directing said blanket along an endless pathway through a plurality of processing positions;
- means for removing a portion of the web-contacting surface of said blanket while said blanket is being directed along said pathway through a plurality of web processing stations, to thereby substantially continuously condition the web contacting surface of the blanket during web processing.
A method of continuously conditioning a rubber blanket on a compressive shrinkage apparatus comprising the step of:
- providing an abrasive roll in line with the web treating pathway of a compressive shrinkage apparatus such that said abrasive roll contacts the web-contacting surface of the blanket and removes a portion of the blanket surface as it travels along its web treating pathway.
An apparatus for continuously conditioning the working surface of an endless rubber blanket on a compressive shrinkage apparatus, comprising:
- a) a first rotatable roll in pressure contact with the web-contracting of said rubber blanket;
- b) a second rotatable abrasive roll in pressure contact with the web-contacting face of said rubber blanket;
- and
- c) means for rotatably coupling said first rotatable abrasive roll with said second rotatable roll, such that rotation of the first rotatable roll causes said second rotatable abrasive roll to condition the surface of the rubber blanket.
