Rollercoater machine for the enamelling of float glass edges

GlassLine is a new machine to enamel the edges of float glass sheets by means of a steel engraved cylinder.
It is a completely new project based on the well-known technologies of enameling by a reverse roller.
Glass line has been designed to provide answers to a peculiar need of glasses bound to building and interior decoration, i.e. the coating of a frame on the four edges of the sheet.
This operation is performed in 4 passes with the return and 90° rotation of the sheet between one pass and the next. After all four sides have been worked, the sheet is sent to the oven for drying.
The machines grants the possibility to enamel sheets with thicknesses from 2 mm. to 25 mm. and sizes up to 2.600 mm. In just one pass, a constant and uniform quantity of enamel can be applied up to 400 g/mq.
The main strengths of the Rollmac machines are their easy use and quick colour change. Small machines can be cleaned and their colours can be changed in just 10 minutes; larger machines require 15 minutes for the same operations.
