Patent ID: 8211001

Claim:
Device to apply sliders ( 32 ) onto closure profiles ( 22 ) comprising different actuator elements ( 110 , 120 , 130 , 140 ) driven by common motor means ( 150 ), said different actuator elements including a spacer ( 130 ) comprising: a central insert ( 132 ) engageable between two profiles of a closure strip and two jaws ( 134 , 136 ) surrounding the insert ( 132 ) and driven alternatively between a clamped position in which the jaws ( 134 , 136 ) clamp support webs of the two profiles against outer surfaces of the insert and a drawn-apart position; a clamp ( 140 ) comprising two jaws ( 144 , 146 ) driven alternatively between a clamped position in which the jaws ( 144 , 146 ) clamp the support webs of the profiles and a drawn-apart position; a pusher ( 120 ) moved alternative in translation to push a slider onto said closure strip profiles, and a driving wheel ( 110 ) driving a chain of sliders ( 32 ) provisionally joined together by scored links ( 34 ) so as successively to transfer each slider ( 32 ) towards a station for their application to the closure profiles ( 22 ), by said pusher ( 120 ), said driving wheel being driven in rotation about an axis parallel to the direction of travel of the closure profiles, a friction brake ( 160 ) acting on said driving wheel ( 110 ), said friction brake comprising two friction washers respectively arranged either side of said driving wheel ( 110 ) and urged towards said driving wheel ( 110 ) by at least one spring ( 172 ) wherein; the device further comprises a screw/nut system ( 174 , 176 ) adapted to act upon a lining of the friction brake so as to form disengaging means ( 170 ) allowing by actuation of said screw/nut system to disengage said lining from said driving wheel ( 110 ) and consequently for disengaging the driving wheel ( 110 ) with respect to the spacer ( 130 ), the clamp ( 140 ) and the pusher ( 120 ).
