SLOT DIE AND INSTALLATION FOR COATING WITH THERMOPLASTIC COATING MATERIAL

摘要

The invention relates to a slot die (14) and an installation (1) for coating a moving web of material (2) with thermoplastic coating material (3). The slot die (14) has two die bodies (70, 71), which can be displaced and/or pivoted in relation to each other by means of a drive (73). As a result, the width (78) of the die gap (77) is adjustable. The discharge of coating material (3) from the slot die (14) can be shut off by means of structures (82) in the die channel (72). A preferred application for the installation (1) in which the slot die (14) is used is the coating of unfinished carpet or synthetic grass (4) with thermoplastic adhesive (hot melt).
