Abstract
Abstract A packaging machine and method for automatic or semi-automatic operation with a bag sealing station provided laterally rearwardly of a bag loading station. A web of interconnected heat-sealable bags are successively fed to the bag loading station. The loaded bag is moved rearwardly to the sealing station and is there clamped against a heater bar by a movable sealing bar. Automatic bag packaging is accomplished by providing a pivotally mounted sealing and detaching assembly which tears the loaded bag from the web during the sealing operation. Heat sealing is accomplished concurrently with separation of the loaded bag from the web. Teeth penetrate the web above the seal to prevent separation of the web at the seal and to assure separation along a preformed line of weakness above the seal. As the sealing bar is released from its clamping position, the web is advanced to move a successive bag into the bag loading position. Semi-automatic bag packaging is accomplished by manually tearing the loaded bag from the web and manually inserting the bag in the sealing station. In semi-automatic operation the web is fed to advance a successive bag to the bag loading position concurrently with the sealing of a bag in the sealing position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A method of packaging comprising the steps of: a. providing structure defining a loading station; b. feeding packaging web along a feed path to the loading station; c. registering a container formed on the web with the loading station; and d. while said container is at the loading station and without moving said container into registry with another station: i. loading said container; ii. closing said loaded container; iii. gripping a portion of said closed loaded container in such fashion as will effectively isolate an adjacent portion of said container from stress producing forces imposed on another portion of said container; and, iv. while said container is so gripped, initiating the performance of an operation on said container which will impose stress producing forces on said another portions, whereby said adjacent portion remains effectively isolated from said forces.
Claim 2
Independent Claim
138 words
A method of packaging comprising the steps of: a. providing structure defining a loading station; b. feeding packaging web along a feed path to the loading station; c. registering a container formed on the web with the loading station; and d. while said container is at the loading station and without moving said container into registry with another station: i. loading said container; ii. closing said loaded container; iii. gripping a portion of said closed loaded container in such fashion as will effectively isolate an adjacent portion of said container from stress producing forces imposed on another portion of said container; and, iv. while said container is so gripped, initiating the performance of an operation on said container which will impose stress producing forces on said another portions, whereby said adjacent portion remains effectively isolated from said forces.
Claim 3
Dependent Claim
143 words
A packaging apparatus comprising: a. means establishing a path of travel for a packaging web to a loading station for positioning a container formed on the web in registry with the loading station; b. closure means operative while said container is positioned at said loading station and without moving said container once it has been loaded and to grip a portion of said closed loaded container in such fashion as will effectively isolate an adjacent portion of said container from stress producing forces imposed on another portion of said container; and c. operating means operative while said container is gripped by said closure means and while said container remains at said loading station to initiate the performance of an operation on said container which will impose stress producing forces on said another portion, whereby said adjacent portion remains effectively isolated from said forces.
Claim 4
Dependent Claim
143 words
A packaging apparatus comprising: a. means establishing a path of travel for a packaging web to a loading station for positioning a container formed on the web in registry with the loading station; b. closure means operative while said container is positioned at said loading station and without moving said container once it has been loaded and to grip a portion of said closed loaded container in such fashion as will effectively isolate an adjacent portion of said container from stress producing forces imposed on another portion of said container; and c. operating means operative while said container is gripped by said closure means and while said container remains at said loading station to initiate the performance of an operation on said container which will impose stress producing forces on said another portion, whereby said adjacent portion remains effectively isolated from said forces.
Claim 5
Independent Claim
161 words
A method of packaging comprising the steps of: a. providing structure defining a loading station; b. feeding a packaging web along a feed path to the loading station; c. registering a container formed on the web with the loading station; and d. while said container is at the loading station and without moving said container into registry with another station: i. loading said container; ii. closing said loaded container; iii. gripping a portion of said closed loaded container in such fashion as will effectively isolate an adjacent portion of said container from stress producing forces imposed on another portion of said container; iv. while said container is so gripped, initiating the performance of a first operation on the adjacent portion of the container; and v. while said container is so gripped, initiating the performance of a second operation on said container which will impose stress producing forces oN said another portion, whereby said adjacent portion remains effectively isolated from said forces.
Claim 6
Independent Claim

Claim 7
Dependent Claim
183 words
A packaging apparatus comprising: a. means establishing a path of travel for a packaging web to a loading station for positioning a container formed on the web in registry with the loading station; b. closure means operative while said container is positioned at said loading station and without moving said container once it has been loaded and to grip a portion of said closed loaded container in such fashion as will effectively isolate an adjacent portion of said container from stress producing forces imposed on another portion of said container; c. first operating means operative while said container is gripped by said closure means and while said container remains at said loading station to initiate the performance of a first operation on said container which will impose stress producing forces on said another portion, whereby said adjacent portion remains effectively isolated from said forces; and d. second operating means operative while said container is gripped by said closure means and while said container remains at the loading station to initiate the performance of a second operation on the adjacent portion of said container.
