Embodiment Construction

[0029] The invention relates to a method for marking substrates obtained by extrusion processes. The marking method according to the invention allows in-line engraving of synthetic profiles in order to obtain various patterns and / or surface textures. The method is more particularly described for marking external parts of watches or jewellery, in particular for marking wristbands of watches or jewellery. However, it can also be applied to the marking of any extruded substrate to produce decorative items.

[0030] According to the invention, the marking is carried out on the synthetic substrate 1 using a marking device 2 which is in-line simultaneously with the extrusion die 3, such as figure 1 shown. Preferably, the apparatus comprises cooling means 4 between the output of the extrusion die 3 and the marking means 2, such as water tanks or channels provided with air jets, which allow the substrate to be slightly cooled after extrusion in order to fix the profile. The device ...

Abstract

The invention relates to an in-line method for marking a substrate (1) made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die (3) to form the substrate (1), marking the substrate (1) by scrolling the substrate (1) obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers (2a,2b) with an upper roller and a lower roller, one of the rollers having an impression (5) forming the negative of a decoration or a texture to be marked on one face of the substrate (1), this same roller or the other of the rollers including at least one notch (6) allowing to guide the substrate (1) as it passes through the extrusion die (3) and between the two rollers (2a,2b). The invention also relates to an installation including in-line extrusion die (3) and the marking device (2).

Description

technical field [0001] The invention relates to a method for in-line marking of synthetic material substrates obtained directly from extrusion dies. Background technique [0002] For marking plastics, several methods are known and used. Mention may be made of embossing, laser engraving or other conventional printing methods. [0003] Laser engraving is the most widely described method of marking plastic. It has several advantages, such as durability and flexibility of patterns to be engraved. The equipment is very expensive in comparison, and most importantly, most plastics cannot be effectively marked without the use of laser-sensitive additives. The choice of additive and laser type is not easy and requires extensive testing for each plastic formulation. [0004] Inkjet and digital printing methods are compatible with online contour customization and allow printing of various patterns. Markers, on the other hand, wear off over time and are therefore not permanent. ...
