Robert E. Coburn - Warminster PA

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B65H 1742

US Classification:

226110

Abstract:

A plurality of flexible panels are disposed side by side and extending in the direction of movement of a web. The panels are supported intermediate their ends by a fulcrum means transverse to the web path. A discrete power means is coupled to each end of each panel for selectively and independently raising and lowering the free ends of the panels while flexing the panels.

Appl. No.:

6/010562

Inventors:

Robert E. Coburn - Warminster PA

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B26D 718

US Classification:

83100

Abstract:

A frame supports an upper set of trim chutes movable toward and away from each other as well as a lower set of trim chutes movable toward and away from each other. The frame supports an upper web support member and a lower support member thereby defining two web paths. Each trim chute has a portion pivotable to an inoperative position wherein the extent to which each end portion projects in an upstream direction is decreased.

Appl. No.:

5/839724

Inventors:

Robert E. Coburn - Warminster PA

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B31B 116

US Classification:

93 582R

Abstract:

Apparatus is disclosed for slitting a web of material such as paperboard utilizing at least two rotatable turrets disposed one above the other. Each turret has a pair of shafts adapted to have blades selectively positionable thereon by way of a master shifter which adjusts the blades for the next production run on one of the shafts which is in an inoperative position while the other shaft on each turret is in an operative position. BACKGROUND Slitting apparatus particularly of the type known as an automatic slitter-scorer which includes either a computer or a mini-processor have been proposed heretofore. See U. S. Pat. Nos. 3,651,723; 3,961,547; 3,646,418; 3,831,502, 3,587,374; 4,010,677; 4,033,217. In the apparatus disclosed in said patents, blades are moved along a shaft to a predetermined position and then secured to the shaft for rotation therewith. There is a need for a slitting apparatus such as a paper-board slitter-scorer which facilitates automatic adjustment of blades disposed in an inoperative position while other blades are in an operative position with respect to the moving web.

International Classification:

B23D 1906
B23D 3500

US Classification:

83504

Abstract:

The tool positioner of a slitter scorer has tool engaging elements which are at least in part cylindrical and coaxial with a piston connected thereto. The cylindrical portion and piston are each independently guided by stationary guide surfaces in order to minimize bending forces on the piston.

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B23D 1906
B23D 3500

US Classification:

83665

Abstract:

A corrugated paperboard slitter scorer has slitting and scoring heads movable individually or as a group along an expandable shaft by way of a master shifter. The expandable shaft provides a friction drag to maintain a head in position until all heads are simultaneously locked to the shaft.

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B31B 102

US Classification:

93 36M

Abstract:

The low speed continuous run feature of a double facer machine is attained by a discrete drive motor coupled thereto by an overrunning clutch. The main drive shaft is coupled to the double facer machine by a fluid operated clutch coupled to circuitry for the double facer machine belt tensioner so that the double facer machine may not operate unless the belt has been tensioned.

International Classification:

B26D 308
B26D 1100

US Classification:

834254

Abstract:

An automatic slitter-scorer apparatus is disclosed for slitting and scoring a corrugated paperboard web. The apparatus includes an upper pair of slitter shafts and an upper pair of scorer shafts, as well as a lower pair of slitter shafts and a lower pair of scorer shafts thereby defining two web paths through the apparatus. The web paths are used alternately. All of said shafts are selectively rotated by means of a single motor at one end of the apparatus. A set of trim chutes is provided for each pair of slitter shafts and is located downstream therefrom.
