Abstract: PURPOSE:To provide an air conveyor device to transport sheet-form objects. which is capable of transporting object quickly and stably for a long distance and holding the object under transport even in the direction against the gravitation CONSTITUTION:Slit-form air jets 6 provided in a nozzle box 4 for jetting the air fed from an air supply source are located on the two sides of a central guide part 8 free from any jet, wherein the headings of the slits are so set that the air jettings incline to both outer sides about the object transporting direction X.

Abstract: PURPOSE:To correctly, easily and finely adjust longitudinal draw ratio to aimed ratio and stabilize the holding of clips by a method wherein the total lengths of (n) chain link units in the grasping and preheating zone of chain links are measured and the interval between guide rails is adjusted so as to bring said total length of each of respective chain links within 1% of the total length, which is determined at the prescribed longitudinal draw ratio and at the same time the difference between the total lengths of the left and right chain links within 1% of each total length of the chain links. CONSTITUTION:The total lengths l1 and l2 of (n) chain link units 3a-3n in the grasping and preheating zone 10 of a left and a right chain links 1a and 1b are measured. Here, let l0 be the prescribed total length on calculation obtained from the longitudinal draw ratio of (n) link units 3, which are assembled so as to be under the state of prescribed longitudinal draw ratio. Firstly, the adjustment is done so as to satisfy relationships ¦l1-lC¦/lC

Abstract: PURPOSE:To make the intersection angle between short links smaller and consequently facilitate the reduction of pitch between grips by a structure wherein special engaging members are provided at the connection part between the short links of pantograph-like link member units. CONSTITUTION:Engaging members 36 are provided at the connection part between the short links 19a and 19b of a link member unit 32 so as to be able to engage with the tooth face formed at the outer periphery of a sprocket 31, which is provided at the starting end of a pitch reduction interval. The intersection angle psi between the short links 19a and 19b can be made smaller without elongating the lengths of the short links 19a and 19b, resulting in enabling to dodge the development of improper length of pitch between grips 3.
