Definitions
- tinplate lids are obtained by usual punching/drawing operations starting with a flat thin metal sheet.
- Said machine comprises a process tank containing an electrophoretic bath, and within which there is arranged at least one conveyor line on which the lids are placed flat with their turned edge facing upwards, and completely immersed in the bath.
- Said conveyor line comprises in particular an endlessly extending horizontal conveyor such as a toothed belt or chain, comprising a plurality of equidistant projecting elements which urge the lids along two opposing longitudinal guides at an adjustable distance apart.
- a part of the electrophoretic bath discharges continuously via these latter into an underlying collection tank, from which it is again returned to the process tank.
- Figure 4 is an enlarged view of the part shown within the circle indicated by IV in Figure 2.
- a tank 3 for containing the electrophoretic bath 4 the tank being positioned between an overlying tank 5 for containing a cleaning liquid 6 ( Figure 3), and an underlying tank 7 for collecting and recirculating the electrophoreti liquid falling from above.
- said apertures 14 are conveniently shaped both to allow passage of the elements described hereinafter and to limit the discharge of liquid 4.
- Said elements comprise for each individual conveyor 44 a longitudinal metal plate 16 for the support and sliding of the conveyor outward branch and two opposing lateral longitudinal metal guides 17.
- Said plate 16 and guides 17 are suitably electrically insulated from the surrounding metal machine components and are preferably constructed of stainless steel or surface treated/hardened steel.
- Each chain 50 passes about sprockets 20, not electrically insulated, and slides in a suitable guide 80 of insulating material which in the lower branch ensures that the appendices or anodes 55 make electrical contact with the upper surface of the lids 8.
