Abstract: The invention particularly relates to a device for placing a slider (1) for actuating closure profiles (P1, P2) of a bag (S), that includes a base, two flanges, and means adapted for respectively urging said closure profiles (P1, P2) towards each other or away from each other on a bag (s), wherein said device includes at least one clamp for retaining the profiles (P1, P2) as well as means for urging a slider (1) towards means (5) for temporarily spacing the flanges of the slider (1), said spacing means including cam paths with a rising slope, characterised in that said means include stowable cams (5) that, in a first non-stowed position interact with said slider (1) so that, during a movement thereof, the inner surface of its flanges is brought into contact with the cam paths progressively moving the same away from each other, and that, in a second stowed position, no longer interact with the slider (1) so that said flanges are brought together.

Abstract: The invention concerns a machine (1) for automatic placement of sliders, including in particular: a first supplier (100) for supplying closure profiles (20), said closure profiles (20) being provided with complementary means (22) allowing the progression of the closure profiles (20) in said machine (1); a second supplier (200) for supplying sliders (10); a device (400) for placing sliders (10); and a separator guide (300), situated opposite the device (400) for placing sliders, said guide (300) comprising a guide channel (310a, 310b) in which the closure profiles (20) progress, the width of said channel (310a, 310b) being smaller than the thickness of the closure means (22), such that when the profiles (20) are brought by the supply means (100) into the separator guide (300), the closure means (22) do not penetrate the guide channel (310a, 310b) while the portion (23) underlying said closure means (22) is squeezed by the walls of the guide channel (310a, 310b), in order to separate the respective free ends

Abstract: A slider chain including a plurality of sliders joined together by divisible bridging pieces (30), and including a linking device at each end in order to interconnect the ends of two slider chains so as to form a longer chain overall. The sliders include an attachment mechanism which is not of cylindrical revolution.

Abstract: The present invention relates to a cursor chain including a plurality of cursors joined together by divisible bridging pieces (30), and including a linking device at each end in order to interconnect the ends of two cursor chains so as to form a longer chain overall, characterised in that it includes attachment means which are not of cylindrical revolution.
