Method and Tool for Embossing
20210187818 · 2021-06-24 ·

The present disclosure relates to a method for embossing a plastic sheet and a corresponding tool (1). The plastic sheet is pressed between first and second tool halves (3, 5) while being heated such that a pattern is imprinted on first and second faces (19, 21) of the plastic sheet. Reference marks (31, 33) are imprinted on both faces of the plastic sheet and the embossed plastic sheet is evaluated optically to determine error data based on the relative position of the first and second reference marks. This allows to adjust the embossing tool based on the error data for subsequent embossing operations.

Method of compressing man-made vitreous fibre web
10920348 · 2021-02-16 · ·

According to the invention, there is provided a method of compressing an uncured man-made vitreous fibre web, the web having two opposed major faces. The method comprising the steps: passing the web along a path; and subjecting the web to thickness compression by applying compression to the two major opposed faces of the web. Compression of each of said major faces of the web is applied by passing the path between converging continuous or discontinuous compression surfaces. Further, the respective major face of the web that is being compressed is in contact with one of the converging compression surfaces, and said converging compression surface is inclined towards the path. Additionally, each inclined converging compression surface applies an amount of compression to the major face of the web with which the respective inclined converging surface is in contact, wherein the amount of compression applied to at least one of the two opposing major faces of the web is adjustable.
