  • Patent number: 6629360
    Abstract: A continuous riveter is provided, which can make a rivet distance in a blind rivet holder small since an available continuous riveter having a linear guide plate elongated from a rivet supply section could not reduce the rivet distance while avoiding the interference with a vertically movable cylinder. A guide plate (43) elongated from an accommodation case (40) of a rivet supply section C is provided with a bent section (43b) inclined at a predetermined angle &agr; with respect to a linear feed section (43a). An axis of a cylinder (31) is disposed on a shank R1 of a blind rivet held by an upper tab T4 of a blind rivet holder T immediately after the rivet holder T has passed through the linear feed section (43a) and bent.

  • Patent number: 6029814
    Abstract: Since a distance of adjacent rivets held by a conventional blind rivet holder was large, a blind rivet holder which is smaller in the rivet distance, and which can accommodate a larger number of rivets in an accommodation case of a continuous riveter is provided. The blind rivet holder is designed to include: upper and lower tabs T4, T5 which are continuously arranged at minute constant intervals with narrow slits T3 formed at upper and lower ends of a perpendicular portion T2 having feeder slots for the blind rivet holder T; through hole s T41 and T51 provided so that a rivet R can be passed through the through hole s obliquely; and an oblique, U-shaped groove T21 provided so as to connect the slit T3 between the adjacent upper tabs T4 to the slits T3 between the adjacent lower tabs T5 and to permit bending from groove as a border.
