An exposure unit (1) for exposing zipper teeth (100) to a treatment of depositing a surface coating film, wherein the zipper teeth (100) have two opposite legs (101), respectively (101 A, 101 B) connected by a bridge (102) which delimits a recess (103) between the legs (101), the exposure unit comprising a metallic or metallised retaining means (10) for retaining the zipper teeth (100) in specific positions, wherein the metallic or metallised retaining means (10) is configured for a force connection by elastic mechanical engagement in the recess (103) between the legs (101) of the zipper teeth (100).
摘要:
A station (10) for dip treatment of chassis (14) on skids (13) comprises a process liquid tank (11), a conveying line (12) for conveying in sequence a plurality of skids (13) inside and outside of the station (10) and a system (21) for vertical movement of a skid (13) conveyed above the tank (11) by means of the conveying line (12), for moving the skid (13) together with the chassis (14) inside and outside of the tank (11). The conveying line (12) comprises roller units (20) for displacing a skid (13), which are movable between an operating position for supporting and displacing the skid (13) above the tank (11), and a retracted non- operating position for immersion of the skid (13) with the chassis (14) inside the tank (11), and the vertical movement system (21) comprises a platform (22) for supporting and engaging with the skid (13), which is mounted on a single, motor-driven, transverse, rotational shaft (23) projecting from the bottom end (24) of at least one vertical support arm (25), the top end of which is connected to a motor-driven vertical travel carriage (26) for the vertical movement of the platform (22) inside and outside of the tank (11).
摘要:
The invention relates to device (1) for applying a liquid or pasty medium (2) to a moving fibrous web (3), in particular a paper, bank note paper, cardboard, or packaging paper web, on both sides, comprising a first application roller (5.1) and a second application roller (5.2), which extend at least over the width of the moving fibrous web (3) and which form a roller gap (N) having a roller inlet area (6), through which roller gap the moving fibrous web (3) can be fed, and comprising a feed device (7) for feeding the liquid or pasty medium (2) into the roller inlet area (6) of the two application rollers (5.1, 5.2), wherein during the operation of the device (1), a liquid sump (8) is formed in the roller inlet area (6) of the two application rollers (5.1, 5.2), through which liquid sump the moving fibrous web runs, and by means of which feed device the level (9) of the liquid sump (8) can be adjusted. The device (1) according to the invention is characterized in that at least one immersion bath device (10) that also accommodates the liquid or pasty medium (2) is arranged upstream from the liquid sump (8) and the roller gap (N) as viewed in the web movement direction (L) of the moving fibrous web (3).
