摘要： PURPOSE:To prepare a spiral pipe having high strength and excellent airtightness, by mounting a nozzle part applying the adhesive supplied by an adhesive supply means to the predetermined position of the strip like body fed by a feed means. CONSTITUTION:A hydraulic motor 53 is driven to rotationally drive a drive roller 51 and a strip like body 90 is fed in a predetermined direction. Further, an adhesive supply pump 70 is driven to apply an adhesive to the engaging groove 95 of the strip like body 90 from a nozzle 75f. The nozzle 75f moves so as to follow the movement of a nozzle guide 75g to be always opposed to the engaging groove 95. The strip like body 90 is introduced into the cylindrical space formed by pipe forming rollers 30 while the unnecessary adhesive thereon is scraped off by a scraping part 78 and forcibly bent in a state contacted with the pipe making rollers 30 under rotation to be spirally wound. One side part 91a of the leading end part of the strip like body 90 is engaged with the engaging step part 94 of the strip like body 90 succeedingly introduced and the engaging rib 93 of the leading end part is engaged with the engaging groove 95 coated with the adhesive and the leading end of the engaging rib 96 of the succeeding strip like body 90 is engaged with the engaging part 92a provided to the side part of the leading part of the strip like body 90 having completed a revolution in the cylindrical space.

摘要： PURPOSE:To easily alter the diameter of the cylindrical space formed by each pipe forming roller, by a method wherein a strip like body is introduced into the cylindrical gap formed by all of pipe forming rollers to be spirally wound while contated with each pipe forming roller under rotation CONSTITUTION:Support levers 25, 26 are moved in a diameter direction corresponding to a spiral pipe to be prepared. The bearings 27, 28 provided to the leading ends of the support levers 25, 26 on the center sides thereof the allowed to position on the concentric circles of annular frames 21, 22 so that the diameter of the cylindrical space formed by pipe forming rollers 30 becomes equal to the outer diameter of the spiral pipe. A handle 43 is rotationally operated so that each pipe forming roller 30 is set at a predetermined spiral angle to allow the annular frames 21, 22 to revolve in directions opposite to each other. A drive roller is rotated to feed a tubular body onto an introducing guide 50 and a strip like body is introduced into the cylindrical space formed by the pipe forming rollers 30 to be contacted with the rollers under rotation so as to always cross said rollers at a right angle and apirally wound at the predetermined spiral angle formed by the pipe forming rollers and the side parts contacted with each other of the strip like body being wound are engaged to form the spiral pipe having a predetermined caliber.

摘要： PROBLEM TO BE SOLVED: To reduce the number of turns of making impulsive sound when transferring bar-like workpieces by receiving the workpiece rolled on a chute by means of a flexible linear or zonal receiving member crossing in a workpiece transferring direction and properly letting out the workpiece receiving member according to the number of the workpieces received for changing the length of the workpiece receiving member. SOLUTION: One end of a wire 20 is fixed to a swing arm 24 through a fixing plate 28. A turning frame 15 and the swing arm 24 are made to approach to rollers 17 and 27 by driving air cylinders 22 and 26, and with the wire 20 turned around a rotary drum 18 drawn out a little, a workpiece W is fed from the rear section of a chute 9 and moved rolling forward. The workpiece W is discharged from the front end of the turning frame 15 and is received mounting on the wire 20. The length of the wire 20 is made long by increasing the drawing quantity of the wire 20 from the rotary drum 18 according to the number of the workpiece W for putting a lot of workpieces W together. After temporarily banding the workpiece W together, the turning frame 15 and the swing arm 24 are made turn upward for taking out the workpieces W.

摘要： PURPOSE: To produce a coated external-wall panel with a paint hardly deposited on the side face by applying a paint on the surface of the panel, then spraying a mixture of the compressed air and fine water droplet on the side face and washing away the paint depositing on the side face. CONSTITUTION: When an external-wall panel 3 on a roll conveyor 2 is moved along a fixed position, the panel is sensed by the photoelectric switch 41 of a detector 4, and the panel width is detected by a photoelectric switch 42. Consequently, a moving nozzle 52 is moved to the optimum position to wash away the side face of the panel 3. The panel 3 is then passed through a coater 1 and passed through a paint dripped in a film form from a paint reservoir 11, hence the surface is uniformly coated with the paint, the surplus paint flows along the side face, and the paint is deposited on the side face. The panel 3 is then passed between a fixed nozzle 51 and the moving nozzle 52, a mixture of the compressed air and fine water droplet is sprayed on both side faces from both nozzles 51 and 52, and the paint depositing on the side face is washed away.
