Devices to apply the tamper-evident ring seal at the base of PRE-THREADED metal screw caps.
Version 1 models are easy to use, twin-lever machines, but each machine is specific for one size of cap only (31.5mm versions can do 18 or 24mm high caps: ‘oil’ caps with or without pourer inserts)
Version 2 is robust and gives an excellent finish, easily adjustable for different cap heights and a range of cap diameters, but slower to use.
Caps must be applied by hand, or using a tightening device, before using the sealer.
Speed 300-800 bottles per hour.
