The invention relates to a method and apparatus for the automatic stuffing o f meat products into a double casing comprising a sheet and a net. The inventi on involves the use of a standard installation consisting of a duly synchronise d stuffing/portioning machine (1) and a rapid fastening device (2), a forming device (3) being disposed therebetween. Said forming device converts the aforementioned sheet (5), which is provided in the form of a roll and which is intended to cover the food products, into a tubular element that can be connected to the stuffing tube (3). A second tube (8) is mounted co-axially to the stuffing tube, said second tube bearing an external casing (9) which is made from a tubular net. The inventive method consists in using tubes (4 and 8) having a reduced diameter, which is much smaller than that of the finishe d product, such that the sheet (5) adapts to the tube (4) following the formation of numerous longitudinal folds therein. Moreover, the reduced diameter of the tube (8) enables the multilayer folding of the tubular net ( 9) by means of the pressure exerted by the pump system of the stuffing machine (1). In this way, both the sheet (5) and the tubular net (9) expand radially and the definitive diameter of the finished product is produced. Said definitive diameter varies according to the speed with which the finished product, which is conveyed by means of an adjustable-speed conveyor belt (12 ), separates from the double fastening device (2).
