Abstract
A method of manufacturing products comprising an outer casing of a first material (12) and containing at least one chamber (18) filled with a second material (14) comprises extruding the first material through a die (10) to form an extrudate body (16) and delivering the second material through at least one fluid outlet (22) in the die to form the least one filled chamber. The extrusion process is varied periodically and momentarily to produce sections (30) of extrudate body having no filled chamber. In one embodiment, the flow of the second material (14) is periodically reduced to form the unfilled sections. The flow of the second material (14) may be reduced by increasing the volume of a supply path for the second material upstream from the die (10). Apparatus for carrying out the method is also disclosed. The method and apparatus are particularly adapted for producing food, and especially confectionery, products.
