摘要：A machine and method for making bags is described and includes a web ,traveling from an input section to a rotary drum, to an output section. The rotary drumincludes at least one seal bar, having a first sealing zone, and an adjacent weakening zone.The weakening zone may be a heated perforator, includes a heating wire, or be disposedto create an auxiliary sealed area. The heating wire can have, connected thereto, a sourceof power that is at an adjustable voltage or magnitude, and/or pulsed, and/or a feedbackloop. The heating wire may be an NiCr wire and make intermittent contact with the weband be disposed in an insert. The weakening zone may create a line of weakness that isuniform or varies in intensity, is a separating zone, or includes a heat film, a toothedblade, a row of pins, a source of air, or a source of vacuum. The sealing zones may includetemperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic,microwave or radiative energy.
