製造に支障を生じたものである。"Conventional technology" Conventionally, when manufacturing lead frames, a band plate with gold plating on the top surface was cut vertically into multiple hoops of the desired width by using a slitter, and when winding the hoops into a fill shape, the top and bottom surfaces of the hoops were wrapped with felt, etc. It is necessary to apply pressure and brake to create tension. However, when the upper and lower surfaces were pressed together with felt, etc., the gold plating on the upper surface of the hoop was damaged, such as abrasions, which caused problems in lead frame production.

。Means for Solving Problems J The present invention provides a hoop receiving surface on the machine frame, the opening of the normal room is in contact with the receiving surface, and the hoop is provided between the outer periphery of the opening and the receiving surface. [Operation J] In the present invention, the lower surface of the hoop 5 is in contact with the receiving surface 2, and the outer peripheral edge 4 of the pressure chamber 3 and the receiving surface are connected to each other. When the hoop 5 is placed in the gap 6 between the hoop 5 and the surface 2, and air is forced into the normal room 3 in this state, the upper surface of the hoop 7-15 corresponding to the opening 3 of the same chamber 3 is pressed downward by the pressure air, and the lower surface of the hoop 5 is received. The air in the chamber 3 is discharged to the outside between the outer periphery 4 of the opening 3 and the upper surface of the hoop 5, and the discharged air is discharged between the outer periphery 4 and the upper surface of the hoop 5. Due to the air layer, the upper surface of the hoop 5 does not touch the outer peripheral edge 4. In this state, by pulling the tool 15, the tool 15 can be tensioned.

である。"Example" In the slitter line, the machine frame 1 is placed in front of the recoiler 7.
A hoop receiving surface 2 made of felt is formed on a horizontal base plate 8 provided on the frame L of the machine. Form this 4. The hoop receiving surface 2 is a rectangular felt horizontal surface that is long in the direction perpendicular to the sliding direction of the hoop 5, that is, the direction of the slitter line. It is formed by a side frame 1O110 and a semicircular side frame 10.10 connecting its ends, and these side frames 10.1
An endless O-ring is disposed on the lower surface of the 0.10S 10 to form the outer peripheral edge 4. A pressure hole 11 is bored in the rectangular plate 9,
A pneumatic air pipe 12 is connected, a straight internal rod 13 is provided on the upper surface, a guide hole 15 is bored in the support plate 14 provided at the upper part, and the guide rod 13 is slidably inserted into the through hole 15. A spring 16 is interposed between the support plate 14 and the rectangular plate 9 to press the air pressure chamber 3 downward. The air pressure sent from the pneumatic pipe 12 increases the pressure inside the pneumatic chamber 3 and causes the rectangular plate 9 to rise against the springs 16.
A passing exhaust gap 6 is formed. Spring 16
The force adjusts the level of the support plate 14 with the cylinder 17 and thereby adjusts the gap 1a'6, determines the thickness of the hoop 5, the gap 6 and the air pressure, and fixes the rectangular plate 9 to the machine frame l. You can also do that. In addition, Monoke receiving surface 2 shown as 18 in the figure
19 is a felt on the upper surface of the hoop, 20 is a free guide roller, and 21 is a brake roller.

上面に損傷を与えるおそれがない。"Effects" Since the present invention is constructed as described above, the lower surface of the hoop 5 sliding on the receiving surface 2 presses against the receiving surface 2 and tension is applied to the tool 15, and the upper surface of the hoop 5 is placed in the pressure chamber 3. Because of the exhaust air layer, it does not come into contact with the outer peripheral edge 4 of the opening of the same chamber 3, and there is no risk of damaging the upper surface of the hoop 5.
