Abstract:
1. Apparatus for producing packets of a flowable material, each of which packets comprises a quantity of said flowable material enclosed within a layer of sheet material, the combination of: fixed means forming a passageway for said flowable material which extends to a discharge opening, means to deliver a series of quantities of said flowable material into said fixed means, said fixed means having an outside surface configuration which is adapted to guide a strip of said sheet material into a tube which has a cross-section area of substantially the cross-section area of each of said packets with the edges of said strip overlapping, means to move a strip of said sheet material onto and thence through said fixed means at a substantially even rate, means to seal said edges of said strip together above the level of said discharge opening thereby to form a filling zone within which said series of said quantities of said flowable material are discharged in a time-separated series into said tube immediately after said tube is formed and means to cross-seal said tube in a predetermined manner away from said discharge opening whereby said tube is adapted to receive each of said quantities of said flowable material enclosed in said tube between two successive cross-sealed portions of said tube.
