Lamination unit feeds components between endless belts - and heaters to press rollers at least one belt being pressed by adjustable force

摘要

The mechanism for laminating e.g. a core between two outer layers using interposed thermo-plastic foils comprises driven upper and lower endless belts to receive the components between them, heating means arranged along at least part of the facing belt lengths, and a pair of pressure rollers at the end of the belts. At least one of the belts is pressed towards the other by an adjustable pressure. This pressure preferably increases in the direction of belt movement and may be provided by members subject to adjustable spring load and possibly contg. heating elements.
