Abstract: A method of making EVA shoe midsole includes a compound containing in percentage by weight the substancessuch as 100% of ethylene vinyl acetate (EVA) into which 5-40% of filling agent, 1-10% of foaming agent, 0.5-3% of bridging agent, 0.5-5% of finishing aid, 0.1-1% of foaming aid and coloring agent are added. Such compound is made into particles to be injected into the primary mold in which the preliminary blank of midsole is formed. The preliminary blank is made to foam to take shape of a molded blank under heat and pressure so as to ensure that the size of the molded blank corresponds to that of the midsole intended to be made. The molded blank is then treated in the secondary mold under heat and pressure and is subsequently cooled to take form of the midsole intended to be manufactured.

Abstract: An automatic assembly system transports workpieces to a work station whereat the workpieces are processed into an assembled product. The automatic assembly system conmprises a monorail that defines a path above the work station. A trolley travels along the monorail supporting a workpiece carrier by means of a pair of latches pivotally connected to the trolley.

The trolley latches retract and the lower mechanism then lowers the carrier and workpieces to the workstation without lowering the trolley or the monorail. A safety interlock prevents uncontrolled lowering of the carrier and workpieces.
