Method for applying and modeling of from an extruded basic material - sealing elements on the surface of a flat or curved layers, and an apparatus for carrying out this method

摘要

A method for applying and modelling seal members constituted of an extruded material onto surfaces of flat or curved sheets is described, the method is characterised in that it comprises the following steps: positioning a sheet (3) to be fitted with a seal member in proximity to a seal member extruding device (1, 16); positioning said extruding device (1, 16) over the sheet (3); extruding a seal member (2) of polymerising material and continuously depositing it on the portion of the sheet (3) that is to be sealed; cutting said seal member (2) of extruded material following the extrusion thereof and before it is deposited on the sheet (3) and in any case before polymerisation thereof takes place, using cutting means (5, 6, 7, 9, 10); and joining and rendering integral with each other the respective initial and final ends of the extruded seal member (2) on the sheet (3), so that one end abuts with the other, using modelling means (8, 13). Furthermore, is disclosed an apparatus for the abovementioned method. IMAGE
