The surfaces of the side tabs that come into contact and the triangular pockets are connected to each other at least in the region of the two folding edges, a connection (32) thus being formed. ## Claims ### Claim 1 A method for forming at least one bottom on a hose piece, which comprises plastic material, in which at least one end of the hose piece is pulled under formation of a bottom rectangle and triangular pockets along at least one first folding edge, for closing the bottom, side tabs of the bottom rectangle are folded back along second folding edges which are at a distance from the first folding edge, wherein the two side tabs subsequently contact one another, and a bottom cover sheet is placed on the bottom and is connected by the action of heat or by a glue to the side tabs and to at least one triangular pocket, wherein the surfaces of the side tabs, which surfaces come in contact, and the triangular pockets are connected at least in the area of the second folding edges, forming a connection with each other. ### Claim 2 (depends on 1) The method according to claim 1, wherein the connection extends at least over an area which is removed by 1 cm from the second folding edge. ### Claim 3 (depends on 1) The method according to claim 1, wherein the connection of the surfaces of the side tabs, which surfaces come in contact, and the triangular pockets comprises at least the area of the particular intersection of the second folding edges and of the diagonals of the triangles. ### Claim 4 (depends on 3) The method according to claim 3, wherein the connection, viewed from the intersection, extends at least 1 cm in the direction of the particular second folding edge. ### Claim 5 (depends on 1) The method according to claim 1, wherein the connection is produced by a hot-air sealing. ### Claim 6 (depends on 1) The method according to claim 1, wherein the connection is produced by an ultrasonic welding. ### Claim 7 (depends on 1) The method according to claim 1, wherein the connection is produced by an application of glue. ### Claim 8 (depends on 7) The method according to claim 7, wherein the application of glue is made before the folding back of the side tabs, preferably before the pulling of the bottom. ### Claim 9 (depends on 7) The method according to claim 7, wherein a heat-activatable hot melt is applied as an application of glue. ### Claim 10 A device for forming at least one bottom on a hose piece, which comprises plastic material, with a bottom opening device for pulling at least one end of the hose piece under formation of a bottom rectangle and triangular pockets along at least one first folding edge, a bottom closing device for closing the bottom with which side tabs of the bottom rectangle can be folded back along second folding edges which are at a distance from the first folding edge, wherein the two side tabs contact one another subsequently, and a cover sheet application device for applying a bottom cover sheet onto the bottom and for connecting the bottom cover sheet to the tabs and to at least one triangular pocket by the action of heat or by a glue, wherein a device for producing a connection is provided with which the surfaces of the side tabs, which surface come in contact, and the triangular pockets can be connected to each other at least in the area of the second folding edges, forming a connection with each other.
