  • Publication number: 20020100155
    Abstract: A machine and a method for assembling a vehicle body is disclosed as including a locating pin (26) formed with a seating flange portion (35) having a work seating surface (35a) and a clamp arm (39) contained in the locating pin to be operable in a clamping or unclamping movement responsive to an extrusion and retraction of a clamp cylinder (34). A detection pin (47) is mounted for an extruding and extracting movement from the work seating surface (35a), with the detection pin (47), a shaft (44) ad a proximity switch (48) forming a work seating detection mechanism (49). A mutual engagement between the locating pin (26) and a locating bore (R) allows a panel W3 to be positioned, simultaneously detecting the presence of seating of the panel W3 responsive to a movement of the detection pin (47).

  • Patent number: 5735112
    Abstract: A yarn heating apparatus, interposed between a false twist apparatus imparting twist to a synthetic fiber yarn and a yarn feed apparatus feeding the synthetic fiber yarn to the false twist apparatus, is designed to heat the synthetic fiber yarn traveling on a yarn travel path extending from the yarn feed apparatus to the false twist apparatus. The yarn travel path includes a twist existence path section through which the twist imparted to the synthetic fiber yarn extends continuously. The yarn heating apparatus comprises a yarn heat member unit formed with a yarn heat channel defining in part the twist existence path section of the yarn travel path for heating the synthetic fiber yarn passing through the yarn heat channel, and a plurality of yarn guide members located in the yarn heat channel of the yarn heat member unit in spaced relationship to one another for guiding the synthetic fiber yarn through the yarn heat channel of the yarn heat member unit.
