摘要： PROBLEM TO BE SOLVED: To prevent the drop of the lubricant applied to the surface of the can component by deairing and injecting the lubricant accommodated in a lubricant accommodation device towards the can component carrier to a processing die by an injecting device so as to transfer the lubricant in a channel smoothly and enable the correct control of the injection pressure and the injection volume of the lubricant. SOLUTION: A device A1 is equipped with a heater 10 and a manifold 11 on the side face of a lubricant tank 3, and injects the lubricant to a scan component 2 from injection guns 24, 25 via the manifold 11. At the time of deaerating the lubricant, the powder lubricant is fulfilled in the tank 3, heated at a proper temperature and molten by the heater 10. Then, a magnet valve attached to the device A1 is actuated based on the signal of a control unit, and a vacuum generating device and the tank 3 are coupled via an intake pipe 8 to deair the lubricant. Thereafter, along with the finish of the setting time, the device is changed to a pressure source by the operation of the magnet valve, so as to complete the preparation of injection. The generation of air bubbles in the lubricant is prevented by the deairing control.

摘要： PROBLEM TO BE SOLVED: To correctly stick a tapelike resin film to a joint part, fill up the step difference of the joint part without a gap to sufficiently cover the metal exposure face, and prevent the gas barrier property of the tapelike resin film itself from being deteriorated more than necessity, in covering the inner face side of the joint part of a can barrel. SOLUTION: As the tapelike resin film 2, a double-layered film provided with a lower layer of a thermoplastic resin having a melting point of 175-225 deg.C to become a sticking face to the can barrel, and a upper layer of the biaxially oriented thermoplastic resin having the melting point of 195-255 deg.C, wherein the melting point of the upper layer resin is higher by 20-60 deg.C than the melting point of the lower lager resin, and the thickness of the lower layer resin exceeds the 60% of the total thickness of the film, is used to preheat the joint part of the can barrel 1. The heating temperature in this process is not within a temperature range from the adhesion start temperature to the melting point of the lower layer resin, and the heating temperature in the process of post-heating of the joint part of each can barrel 1 stuck with the tapelike resin film 2 is set at the temperature or higher than the melting point of the lower layer resin and less than the melting point of the upper layer resin, and the post-heating process is conducted in a state of nonpressing against the stuck tapelike resin film.
