Patent ID: 7992615

Claim:
An apparatus for manufacturing a shock-absorbing packing material inflated with air, comprising: roll units ( 10 and 10 a ) installed at a predetermined distance on which plastic sheets or films ( 1 ) are rolled; a roll unit ( 10 b ) that is disposed between the roll units ( 10 , 10 a ) and provided with a roll around which a valve film or sheet ( 2 ) is rolled; unrolling tension control units ( 20 , 20 a , and 20 b ) that applies shock absorption to the sheet or film ( 1 , 2 ) unrolled from the roll units ( 10 , 10 a , and 10 b ); a compiling unit ( 30 ) that compiles the shock-absorbed sheet or films through the unrolling tension control units ( 20 , 20 a , and 20 b ); a sealing unit ( 40 ) that applies heat to the sheet or films compiled at the compiling unit ( 30 ) to form a desired-shaped shock-absorbing packing material; a cooling unit ( 50 ) that cools the heat-sealed shock-absorbing packing material at the sealing unit ( 40 ); a wiring tension control unit ( 60 ) that applies shock absorption to the shock-absorbing packing material conveyed from the cooling unit ( 50 ) after cooling; and, a re-rolling roll unit ( 70 ) that is disposed at a rear side of the wiring tension control unit ( 60 ).
