Abstract
In a method of shrinking screw caps (2) on to the mouths (1) of containers (13), the screw caps are acted upon by a hot gas jet (7, 8) from nozzles (3, 4), along a feed path (6), from both sides. The flow axes (7, 8) are displaced relative to each other so that there are no pressure build-up and stagnation effects. The resulting advantageous temperature pattern at the nozzles means that savings in heating output can be attained. In addition, there is no longer any need for the bottles to be rotated about their own axis (10).
