Claim 1
Independent Claim
162 words
A machine for forming packages from a web of interconnected preformed bags comprising: a frame that supports an pivot tube; a load section pivotally mounted on the pivot tube; the load section comprising transport belts that grip the web, the transport belts being routed to open bags of the web for loading and being routed to close the bags after the bags have been loaded; a closure section mounted to the pivot tube, the closure section includes heater belts that feed the web through the closure section and a heat source assembly that seals the web that passes through the closure section; wherein the transport belts of the load section are pivotable with respect to the frame independent of the heater belts of the closure section; and wherein the transport belts and the heater belts are driven by a common drive and the drive is disconnected from the heater belts when the transport belts are pivoted with respect to the heater belts.
