Arrangement of a bellows for a container of a balance

摘要

Bellows arrangements of this type must, on the one hand, be flexible enough not to form a syphoning effect. On the other hand, they must have sufficient strength, in particular impact strength, for example an impact strength of 10 bar atmospheric pressure is required. According to the invention, a bellows arrangement of this type consists of a highly tear-resistant fabric (21) which is coated on both sides. The inner coating of the highly tear-resistant fabric (21) consists of a silicone film (20) bonded to the fabric (21) and the outer coating of a silicone coating (22). The highly tear-resistant fabric (21) is processed diagonally, from the cylindrical part of the connection bellows it merges integrally into flange-type connection parts (2) which the connection bellows has on each side. These connection flanges (2) have a bead-type reinforcement (3) on the circumference. Said reinforcement is expediently a silicone cord (4) bonded to the highly tear-resistant fabric (21). IMAGE
