Appl. No.:

09/547572

Inventors:

John Simonetti - Deer Park NY
Peter Terranova - Howard Beach NY

Assignee:

Ro-An Industries Corp. - Maspeth NY

International Classification:

B31C 100

US Classification:

493269, 493 22, 493189, 493209, 493242

Abstract:

The present invention relates to a âpolyâ bag machine and, more particularly, to mechanisms for operating the seal bar component of such machines. The machine according to the invention includes a mechanism for reciprocatingly raising and lowering the sealing bar in which the movement and position of the sealing bar are controlled by the drive shaft and are selectively adjustable by one or two separate servo-drives. A main link is coupled to a seal bar drive shaft for movement in direct response to its rotation. A second link is movably coupled to the main link. A servo-drive system including a servo motor or servo valve is coupled to the second link for adjusting the position of the second link with respect to the main link while the main link is moving in response to the rotation of the drive shaft.

US Classification:

226 31

Abstract:

A split bag making machine includes a first primary split draw roller and a second primary split draw roller, each having first and second web contacting sections which are independently rotatable, the first section of the first primary split draw roller being in rolling engagement with the first section of the second primary split draw roller at a first nip, the second section of the first primary split draw roller being in rolling engagement with the second section of the second primary split draw roller at a second nip. A first servo motor is coupled to the first web contacting section of the first primary split draw roller, and a second servo motor is coupled to the second web contacting section of the first primary split draw roller. The respective rotational speeds of the first and second servo motors are controlled by a controller. The split bag making machine also includes a secondary split draw roller positioned upstream of the primary split draw rollers, the secondary split draw roller having a first web contacting section corresponding to the first web contacting sections of the primary split draw rollers and having a second web contacting section corresponding to the second web contacting sections of the primary split draw rollers.
