procedure and device for application of a to a foil formed elastomer during biaxiell route on a pellet for analysis of in elastomeren conclusion the spridningsgrad

摘要

Holding a membrane-like sample (3) of elastomeric (preferably rubber) film over of a cylinder (7) used to stretch it biaxially for elastomer material analytical purposes comprises biaxially stretching the sample in the plane of the film whilst forcing hydraulic fluid (preferably compressed air) between the sample and cylinder and then evacuating the fluid so that the sample surrounds the cylinder.The device for carrying out this method is also claimed.
