FIELD: transport, package. ^ SUBSTANCE: proposed device relates to covers with detection of tamper, particularly to the device and method of curling flange plug on signaling rim of the cover with detection of tamper. Positive effect results from using the device for curling flange plug on the covers with detection of tamper from the as-moulded position directed outward along the axis into position of use directed inward along the axis. Proposed device comprises cover support base wherein as-moulded flange plug is spaced apart from said base and turned from it. Said support base is provided with jamb to be located into position spaced apart from said support base. Said jamb has guide ring that moves together with said jamb to grip cover flange plug located on support base and to bend flange plug radially inward. To move through guide ring, there is a banding ring intended for gripping and curling of flange plug radially inward and into position of use oriented along the axis. ^ EFFECT: method and device to curl flange plug on large-diametre cover. ^ 13 cl, 12 dwg |
