<p>PURPOSE:To melt-stick a melt-sticking member and a member to be melt-sticked uniformly without melt-sticking defects, by press-contacting and rotating them automatically while changing pressure in case of the frictional melt-sticking between thermoplastic resin members. CONSTITUTION:A rotary cylinder 1 incorporating a rotation shaft 19 is connected to a rod 24 of an air cylinder 23, and a thermoplastic resin member 21 to be frictionally melt-sticked is attached to the tip of the rotation shaft 19. High-pressure air is supplied to the air cylinder 23 to allow the rod 24 to fall, and the melt-sticking member 21 at the tip of the rotation shaft 19 is pressed to a member to be melt-sticked. Next, low-pressure air is supplied to the air cylinder 23 to bring both members into contact with each other with a proper pressure, and the melt-sticking member 21 is rotated by the rotation of a motor 8 to soften frictionally both members to be melt-sticked to each other. The rotation of the motor 8 is stopped, and air supplied to the air cylinder 23 is switched to high-pressure air to press both members to each other strongly, thus press-fixing them. This operation is performed by an automatic switching operation to form a melt-sticking part having a uniform and excellent quality.</p> |
