  • the conveying portion to the drying station R4 is provided with 62 blades with a blade spacing of 571 mm. and blade length of 2,240 mm., as for R1 and R3 rollers (R2 rollers are longer, due to the operating requirements of the preheating system, as will be later explained); each blade is supported by four bearings on the hinges 13 for the advancing chain of the type 1 - 1/ 2" as for the roller transmission chain.
  • the conveyor R4 is also provided with a guide chain of 1-1/4".
  • the conveyor R4 presents in the specific case a length of 17.4 m, whereas the drying station E presents a length of 14 m so that there will be a projection of the conveyor 4 of more than 3 m from the front to serve the painting station P as represented in Fig. 10 and for this purpose not represented for simplification but separately represented in a larger size in Figs. 8, 9.
  • each chain conveyor chain moves on two wheels, one of which is driving and the other is loose and is supplied with a stretching device structured and placed according to well known shape and not represented.
