摘要

Disclosed is a slot die comprising a die body including: a feed unit to which a coating material is introduced; a chamber for accommodating the coating material supplied by means of the feed unit; a slit that communicates with the chamber so as to enable an outflow of the coating material; and a die lip for forming the slit. The chamber includes a chamber block which has an internal space for accommodating the coating material and which is arranged such that the whole of the block can be replaceable in the die body. A coating width is determined by the width of the internal space of the chamber block.
