Abstract:
A method for force-tightly attaching a tubular piece made of elastomeric material to a connecting part, the method comprising the steps of:pushing an open end of said tubular piece onto said connecting part so that a pushed on end region of said tubular piece is on said connecting part; positioning a metal clamping ring around said tubular piece at the pushed on end region thereof; radially applying a clamping force (K) during a clamping operation to said clamping ring to reduce the diameter of said clamping ring and thereby tightly clamping said tubular piece on said connecting part; detecting the radial clamping force developed during the clamping operation between said clamping ring and said tubular piece; observing and measuring a force/displacement curve during said clamping operation; and, utilizing a characteristic feature of maid force/displacement curve as a basis for a criterion for switching off the application of said clamping force.
