Automatic sleeve wrapping machine BVM Brunner

The BVM stretch banders use an upper and lower film roll. In conjunction with a film stretching device a tight film sleeve is produced around the product.

The film is stretched by means of rubber wind-back rollers, the degree of stretching being infinitely adjustable. With this system it is possible to stretch wrap product stacks or multipacks of e.g. bottles or cans without shrinking. Alternatively a following shrink tunnel can be used as well.

Function
The products are fed via transport conveyor in line or at right angles. The multipack is either formed in the machine or it arrives already pre-grouped by the customer. The sleeve sealing machine or the stretch bander is using an upper and lower film roll which are welded as a so-called „film curtain". During the transport resp. infeed movement a film sleeve is sealed around the product. In the following shrink tunnel the products are shrunk to a stable multipack which can be safely transported. The shrinking result can be regulated within the heating zones by means of an electronic temperature regulation and adjustable air flaps.
