Abstract

It is known to pack stacks with shrink foil in the form of a hood which is manually drawn over the stack at one work station, and then which at a second work station is exposed to the influence of heat so that it shrinks around the stack. The present invention discloses a method and an apparatus whereby the covering and the shrinking are effected at one station and in a fully automatic manner, in that a foil is fed from a supply roll (4) from above and down to a shrink frame (1) which is vertically movable, and which with its downwards movement is used to draw the hood down after cutting-off and spreading, and which during its movement upwards carries out the shrinking.
