帘幕涂覆器
摘要：
本发明涉及一种用于用至少一种液态至膏状的涂覆剂（3、3a、3b至3n）对运行中的纸张幅材、卡纸幅材或其他纤维材料幅材（2）进行涂层的帘幕涂覆器（1、1a、1b），其包括在纤维材料幅材（2）上方且与其间隔布置的机器宽的带有至少一个涂覆剂腔（7、7a、7b）的涂覆头（4、4a、4b），各至少一个用于相关的被输送的涂覆剂（3、3a、3b至3n）的开口（8、8′至8″′、8b至8n）通到该涂覆剂腔中，其中，涂覆头（4、4a、4b）以自由下落的帘幕（9、9a、9b）形式将至少一种涂覆剂（3、3a、3b至3n）放出到纤维材料幅材（2）上，并且其中，涂覆头（4、4a、4b）或开口（8、8′至8″′、8b至8n）与至少一个涂覆剂输送管路（10）连接，用于聚集或缓冲、排气、过滤、调温、调量等的不同的设备（11）联结到该涂覆剂输送管路中。根据本发明，为涂覆剂（3、3a、3b至3n）设置有至少一个过滤器（13、13′、13″、13″′），所述过滤器直接与开口（8、8′、8″、8″′、8b至8n）连接。
摘要（英）：

The invention relates to a curtain applicator (1, 1a, 1b) for coating a moving paper, cardboard or other fibrous material web (2) with at least one liquid to paste-like application medium (3, 3a, 3b to 3n), comprising a machine-wide application head (4, 4a, 4b), which is arranged above the fibrous material web (2) and at a distance therefrom and has at least one application medium chamber (7, 7a, 7b), into each of which at least one opening (8, 8' to 8''', 8b to 8n) for the respective supplied application medium (3, 3a, 3b to 3n) opens, wherein the application head (4, 4a, 4b) delivers the at least one application medium (3, 3a, 3b to 3n) in the form of a free-falling curtain (9, 9a, 9b) onto the fibrous material web (2), and wherein the application head (4, 4a, 4b) or the opening (8, 8' to 8''', 8b to 8n) is connected to at least one application medium supply line (10), into which various means (11) for collecting or buffer-storing, ventilating, filtering, temperature-controlling, quantity-regulating and the like are incorporated. According to the invention, at least one filter (13, 13', 13'', 13''') is provided for the application medium (3, 3a, 3b to 3n), said filter being directly connected to the opening (8, 8', 8'', 8''', 8b to 8n).
