  • Patent number: 4449742
    Abstract: A flexible sleeve type connecting structure, especially for connecting an inlet and/or outlet of a movably supported weigh hopper to other stationary scale components, includes a sleeve (1) made of a flexible webbing. The outer surface of the webbing sleeve (1) is provided with a silicone coating. The inner surface of the webbing coating has bonded thereto a layer or film of silicone by a suitable adhesive. The strands in the webbing extend at about 45.degree. relative to the longitudinal axis of the sleeve for an improved flexibility. Each end of the sleeve has a flange (2, 2') extending radially outwardly and merging into a bulging ring (3, 3') at the radially outer edge of the respective flange. The webbing forms an integral part of the sleeve, of the flanges and of the bulging rings which are received in grooves of respective mounting members (10, 10').
