Abstract
Abstract Apparatus for the automatic manufacture of thermoplastic carrier bags of the type formed of thin film of thermoplastic material and having a thermoplastic handle and closure means secured to the inner walls of the bag at its mouth. The machine includes apparatus for transporting a double layer bag blank of thermoplastic material, inserting a combined handle and closure means into the open edge of the blank and heat sealing each side thereof to a respective wall of the blank. Thereafter, the bag blank, with handle and closure means attached thereto, is transported to a further station at which a combined sealing and cutting operation occurs to form separate bags whose side edges are now sealed. A magazine is provided for storing a plurality of such handle and closure means and means is provided for feeding one at a time into the bag blank. The apparatus includes means for adjusting in a plurality of different ways the position of each handle and closure means as it is fed into the bag blank.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
277 words
Apparatus for the automatic manufacture of bags having handles secured to the inside bag walls at the mouth of the bag comprising in combination, means for intermittently moving a double layer bag blank in the form of a continuous web past a handle inserting and securing station, handle inserting means mounted for movement in the direction of travel of the web and including a magazine for storage of a plurality of said handles in stacked relationship, said last-named means intermittently and in timed relationship to the movement of said web moving at least one handle into the web mouth, means exteriorly of said web for securing said handle in said bag web to a wall of the bag blank, means for sealing said web at spaced intervals to form successive bags and also to separate said successive bags, said web and said handles both being formed of a thermoplastic material and said handle inserting means supporting heat sealing means which intermittently contacts at least one outer surface of said web to heat seal it to the handle inserted between the layers of said web, each said handle comprising two detachably secured portions each having a longitudinal sealing strip and said heat sealing means comprising two longitudinal heating bars and means for moving said two bars simultaneously toward the plane of said web to heat seal each layer of said web to a respective sealing strip, each said heating bar being mounted adjacent the end of at least one pivotally supported rocker arm, and means for at times rotating both said rocker arms through equal arcs to move said heating bars relative to the plane of said web.
Claim 2
Dependent Claim
277 words
Apparatus for the automatic manufacture of bags having handles secured to the inside bag walls at the mouth of the bag comprising in combination, means for intermittently moving a double layer bag blank in the form of a continuous web past a handle inserting and securing station, handle inserting means mounted for movement in the direction of travel of the web and including a magazine for storage of a plurality of said handles in stacked relationship, said last-named means intermittently and in timed relationship to the movement of said web moving at least one handle into the web mouth, means exteriorly of said web for securing said handle in said bag web to a wall of the bag blank, means for sealing said web at spaced intervals to form successive bags and also to separate said successive bags, said web and said handles both being formed of a thermoplastic material and said handle inserting means supporting heat sealing means which intermittently contacts at least one outer surface of said web to heat seal it to the handle inserted between the layers of said web, each said handle comprising two detachably secured portions each having a longitudinal sealing strip and said heat sealing means comprising two longitudinal heating bars and means for moving said two bars simultaneously toward the plane of said web to heat seal each layer of said web to a respective sealing strip, each said heating bar being mounted adjacent the end of at least one pivotally supported rocker arm, and means for at times rotating both said rocker arms through equal arcs to move said heating bars relative to the plane of said web.
Claim 3
Dependent Claim
61 words
The apparatus of claim 1 in which said rocker bar rotating means comprises a cylinder, a crank arm rotated by actuation of said cylinder, a cam member guided in a slot which permits cam movement only in a direction substantially in the plane of said web, and a pair of links coupling said cam member to each of said rocker arms.
Claim 4
Dependent Claim
210 words
Apparatus for the automatic manufacture of bags having handles secured to the inside bag walls at the mouth of the bag comprising in combination, means for intermittently moving a double layer bag blank in the fOrm of a continuous web past a handle inserting and securing station, handle inserting means mounted for movement in the direction of travel of the web and including a magazine for storage of a plurality of said handles in stacked relationship, said last-named means intermittently and in timed relationship to the movement of said web moving at least one handle into the web mouth, means exteriorly of said web for securing said handle in said bag web to a wall of the bag blank, means for sealing said web at spaced intervals to form successive bags and also to separate said successive bags, and means exteriorly of said web becoming at times effective to exert a frictional restraining force against movement of said handle in response to said handle inserting means through the intervening material of the web, said restraining means including a pressure plate, a solenoid for at times actuating said pressure plate, and a spring for moving said pressure plate in a direction opposite to that imparted to said plate by said solenoid.
