Claim Text:
1. An apparatus for manufacturing mesh bags from a roll of continuous mesh tube by means of repeating operation of sewing across the mesh tube and cutting the sewed mesh tube into segments, the apparatus comprising: a number of guiding rollers affixed to a machine frame, said guiding rollers defining a passageway through which the mesh tube being transported from one end to another end of the apparatus, and at least one of said guiding rollers being motor-powered to drive the mesh tube's transportation; a guiding assembly which comprises a partition plate, at least two adjustable arms for propping up the mesh tube, at least one free spinning support roller and a supporting member for coupling said partition plate, said propping arms and said free spinning support roller together, said guiding assembly being dynamically coupled in said passageway through rotating interaction between said free spinning support roller and at least one said guiding roller, said guiding assembly being placed inside of the mesh tube and separating the mesh tube into two opposite sides, one of which passing between said free spinning support roller and said at least one guiding roller; a film attaching assembly for attaching a band of plastic film to a first portion of the mesh tube which is separated by said guiding assembly; a label attaching assembly for attaching a preprinted label to a second portion of the mesh tube which is separated by said guiding assembly or to a filmed portion of the mesh tube; and a hole-punching assembly for punching holes on another filmed portion of the mesh tube, said hole-punching assembly comprising a pair of male cylindrical members and a heating means for heating said cylindrical members, said cylindrical members being operable to be coupled into a pair of through-holes on said partition plate to make a pair of holes on two opposite sides of the mesh tube separated by said partition plate, said through-hole's diameter being slightly larger than said male cylindrical member's diameter; wherein the mesh tube is transported through said passageway at a predetermined speed and pauses at predetermined intervals and said label attaching assembly's operation, said film attaching assembly's operation and said hole-punching assembly's operation are performed during each paused interval; and wherein any of said label attaching assembly, said film attaching assembly and hole-punching assembly can be disengaged from operation pursuant to the mesh bags' specification.
