Abstract:
In apparatus for and a method of sealing mounts to fluorescent lamp tubes on horizontal sealing machines each sealing head has a mount holding member pivotable between a mount sealing position in which it is coaxial with the lamp tube and a mount loading position which is angularly displaced by about 90 DEG in a plane normal to the direction of travel of the sealing heads from the mount sealing position and in which it can accept mounts from a mount conveyor externally of the sealing machine.
Abstract:
Lames de revêtement électrostatique (11) servant à enduire des objets d'un liquide. La lame est formée de deux moitiés (12a et 12b) maintenues l'une contre l'autre par des boulons (15). Un passage central (14) reçoit du liquide provenant d'un réservoir (ne figure pas sur l'illustration) et un canal étroit (16) peut conduire le liquide jusqu'à un tranchant d'écoulement (17). La lame peut être utilisée horizontalement (comme c'est l'habitude pour les lames de revêtement électrostatique) ou verticalement. Les lames (11) sont particulièrement utiles lorsqu'elles sont disposées verticalement afin d'enduire d'huile les bords de rouleaux de tôle.
Abstract:
Electrostatic coating blade and method of electrostatic spraying An electrostatic blade is disclosed having a slot extending the length of the blade and leading from a central duct to an outlet A surface made of non-conductive material extends in front of the outlet and terminates in a discharge edge which is spaced 0.05 to 4mm from the slot outlet In use, liquid is passed from the duct along the slot to the outlet where it collects as a bead. An electrostatic field is applied between the liquid at the slot outlet and the object to be coated which draws liquid along the non-conductive surface in a tapering stream and further causing the liquid to be discharged from the edge Because the stream of liquid reaching the discharge edge is very thin, very low liquid discharge rates can be achieved while still maintaining a uniform coating on the target object.
