<p>In warehouse and other goods entrances where vehicles are loaded and unloaded, the seal is for the gap between building and vehicle or container, with the effective surface in contact with the latter elastically resilient and movable towards the building. The interval between seal and building (1) can be reduced independently of vehicle or containers, and the seal can be fixed in this reduced interval position. It can be sited in an end position close to the building and led along by cable traction, pref. with a calb e(18, 21) engaging each side with w inch (20) for cable shortening. This prevents risk of damage to the seal when the height of the vehicle varies as it approaches or leaves.</p> |
