The toughening line with spindles is suitable for all kinds of articles, but it is especially suitable for tall, narrow unstable glass shapes (stemware), such as drinking glasses and cups.
The line with spindles used for unstable ware is made up of ware carrier chain, which passes through heating and homogenisation zone into tempering and cooling zone.
During the movement of articles through the line, the baskets are rotating to assure better temperature homogenisation.
Heating is provided at the tunnel sides by gas or electricity.
Loading and unloading units are also designed and produced at Vidromecanica.
