A foaming apparatus for refrigerator cabinets and the like, of the type comprising a foaming jig provided on a frame movable from a lowered position, for loading and unloading the cabinets, to a raised position in which the jig cooperates with a plug member in order to oppose the thrust on the external and internal walls of a refrigerator cabinet during the foaming. The improvement consists in the fact of providing a rotatable plug-holder, revolving on a horizontal axis and provided with angularly spaced plug members each of which can be positioned each time over the foaming jig.
