Abstract
Abstract The invention relates to packaging machines wherein a web of flexible material is transformed into a tube, filled, sealed and discharged onto a conveyor mechanism, the completed package being then transported to a positioning device where it is deposited in a shipping case. The packaging and shipping case loading machines are coordinated by a plurality of sensor means which preclude the necessity of an operator having to start and stop the machines when a filled shipping case is removed from the platform and supplanted by an empty one.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
138 words
A packaging machine comprising a system for continuously fabricating packages and of a device for introducing the same sequentially by means of a positioning and deposition head into a shipping case and of a conveyor system for bringing these packages spaced from each other from the packaging machine to a shipping case loading machine, characterized in that a barrier member is mounted adjacent to the starting end of said conveyor system from the packaging machine to the shipping case loading machine, said barrier member being brought into a substantially horizontal package retaining position whenever a given number of packages has passed a counter associated with the shipping case loading machine, said counter further effecting shut-down of the operation of the packaging machine and interrupting operation of the positioning and deposition head that loads packages into the shipping case.
Claim 2
Dependent Claim
