Abstract: A bag component for a product includes a first plastic film and a second plastic film. A product space is delimited by mutually opposite sides of the first plastic film and the second plastic film and a circumferentially closed boundary. The first plastic film and the second plastic film are joined along a first portion of the boundary. The first plastic film and the second plastic film form a reception space for the product and/or an insert component along a second portion of the boundary. At least one of the first plastic film and the second plastic film has at least one recess in or adjacent to the second portion of the boundary. A method for manufacturing a bag component includes forming a plastic film. A forming tool for forming at least one recess in at least one plastic film of a plastic film arrangement includes a forming surface.

Abstract: This device comprises a frame carrying means for conveying blanks according to a substantially plane path and two parallel shafts (10, 11), which are mounted so as to be rotatable on both sides of the plane of said path and comprising tool supports (19a, 19b, 20a, 20b) for inducing a shearing between the adjacent edges of a cutting line during their displacement, in order to break nicks on the cutting line. Each parallel shaft (10, 11) comprises at least one tool support (19a, 19b, 20a, 20b) for connecting the shearing tools to said respective shafts (10, 11) and means for angularly (10a, 11a) and longitudinally positioning these tool supports (19a, 19b, 20a, 20b) on said respective shafts (10, 11).
