<p><P>PROBLEM TO BE SOLVED: To provide a bag making apparatus with a simple configuration that: prevents fluctuations in tension; allows the setting of precise initial conditions; reduces or makes unnecessary monitoring during continuous movement, and time and structures for adjustment; allows increased film material feed rate; and improves the efficiency of production. <P>SOLUTION: This bag making apparatus 100 for packaging containers includes: a tension-controlling means 165 for controlling the continuous feed rate according to the values detected by a tension sensor 164 of a tension-detecting roll 163. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
