Abstract: PURPOSE: To improve the finishing shape of the strip, and to reduce the rolling power, by automatically regulating the uncoiling and coiling tensions of the strip mill correspondingly to the difference between speeds of upper and lower reducing rolls of the mill.   
     CONSTITUTION: The strip 3 is uncoiled by the uncoiling reel 4, and is rolled by upper and lower  reducing rolls 1, 2, and is coiled by the coiling reel 5. Upper and lower reducing rolls 1, 2, are  driven by motors 6, 7, whose speeds are controlled by the speed controllers 10, 11, correspondingly to the speed data being set in the setters 14, 15, for speeds of upper and lower reducing  rolls. The uncoiling reel 4 is driven by the motor 8 whose current is controlled by the current controller 12 to a value equal to the set data for the current value to be produced from the current set  corrector 18. The corrector 18 takes in the set data for the speed of upper reducing roll 1 from the  setter 14, and the set data for the speed of lower reducing roll 2 from the setter 15, and detects  the difference between these two set data for speeds of upper and lower reducing rolls 1, 2, and  corrects the current being set in the current setter 16 according to above detected diference, and  inputs the corrected current data into the current controller 12 as the corrected data to be set.  Thus the current of the uncoiling motor 8 is changed according to the speed difference between  two reducing rolls 1, 2, and the uncoiling tension is also changed.

CONSTITUTION:A metal piece 33, whose diameter is larger than the shape of a lead wire by 4-5 times, is fixed on an electrode 32, which is printed on a thick film substrate 31 by way of a soldering layer 34. The lead wire 36 is fed from a pool 35 and contacted with the surface of the metal piece 33 at a right angle. The lead wire is pushed by specified pressure (7-9kg). A specified welding current (1-2kA) is made to flow in a short time and welding is performed. Welding electrode 37a and 37b hold the lead wire 36. Grounding electrodes 38a and 38b compress the lead wire on the metal piece 33, and the welding current is made to flow.
