Patent number: 5862724Abstract: When a screw 14 is driven into workpieces 61 and 62, it is possible to reduce any reaction that a driver bit 11 is raised so as to obtain fast and reliable screw driving. In the screw driving method of the present invention, the screw is advanced with a strong pressing force of 7-10 Kg during a period from disengagement step of the screw from a carrier strip 14 to driving step of the tip of the screw to the predetermined depth (the lower surface) of the workpiece 61. When the screw is screwed into the workpiece 62, the driver bit 11 is advanced with a weak pressing force of 2-3 Kg. In a screw driving apparatus of the present invention, the fitted screw is disengaged from a screw carrier strip by means of a forward stroke force of the driver bit. The tip of the screw is driven to a predetermined depth in a workpiece. During the term between the disengagement and the driving of the screw, the driver bit is advised with a strong pressing force by a primary piston 26.Type: GrantFiled: October 8, 1997Date of Patent: January 26, 1999Inventors: Ken Arata, Satoshi Fujii
