It is reported that bag making machine is applied to manufacturing and printing the uncolored vest bags made of HDPE, LDPE roll films and PE Stretch Wrap Films. It adopts PLC control, double servo motor fixed length and the liquid crystal touch screen actual display to finish the feeding, sealing, cutting, punching holes and transporting only in one process. It is of high degree of automation and good economic result. As a hand quilter I have gotten in the habit of carrying my cut pieces in a plastic bag. Threads also do well in plastic bags as the thread slides easily through the sealer part of the bag while holding the other spools of thread. However, the machine can also be employed if the tubular bags to be manufactured are to be of greater width than afore-mentioned and if sealing of the longitudinal joint is affected in a manner other than by an entrained internal seal strip, such as, for example, by overlapping strip edges.
Bag making machine of this type is generally satisfactory in operation. However, problems are involved with preparing the machine, in particular, the special type of bag making machine, for operation and start-up, as the Stainless Steel Circle Cutting Machines are directly introduced into the cutting means. However, the foil is discharged behind the said cutting means in the form of strips cut in parallel. This means that each of the suspending strips, before start-up of the machine, is to be carefully placed manually in abutment with the respective tube to then mount the elements and start the actual operation of manufacturing the bags which, incidentally, remain one-sided open and unloaded to be subsequently filled and closed in a separate loading and sealing machine.
