Method for producing a casing
In a process for the manufacture of packs, for a product in portions, with a paste-like product that is to be packaged, especially sausages, in a foil tube ( 15 ), starting from a band-shaped flat foil ( 1 ), which has been provided unilaterally with a connecting layer, this flat foil is unwound from a stock supply ( 2 ) and bent in the longitudinal direction to form the tube in such a way that the connecting layer is located on the outside, and the longitudinal sides ( 10 ) of the longitudinal edges ( 9 ) are located opposite one another, after which a strip ( 12 ), which is capable of forming a connection or which is provided with a connecting layer, is placed in the longitudinal direction over both longitudinal edges ( 9 ) and is connected to them, after which the foil tube ( 15 ), which is formed in this way, is then filled directly with the product that is to be packaged.
1. Process for manufacturing packs for packaging a pastry product in portions, in a foil tube comprising the steps of:
providing a band-shaped flat foil having longitudinal sides of longitudinal edges, and said flat foil comprising a sealing layer on one side, whereby said flat foil is unwound from a stock supply, and
forming a strip by severing a strip of material from a longitudinal edge of said band shaped flat foil, and
bending the remainder of said flat foil in the longitudinal direction to form the tube with the sealing layer on the outside, and the longitudinal sides of the longitudinal edges located opposite one another, and
placing the strip upside down on the outside surface of the tube in the longitudinal direction over both the longitudinal edges, and
sealing said strip to the longitudinal edges to form a connection with the outside surface of the tube, and
filling the foil tube ( 15 ) directly with the product that is to be packaged.
2. Process according to claim 1 , wherein the flat foil ( 1 ) consists of a material with a surface to which a raw sausage composition can adhere.
3. Process according to claim 1 , wherein said strip ( 12 ) is severed from said band-shaped flat foil ( 1 ) while said band-shaped flat foil is being unwound.
