US Patent:

44159781, Nov 15, 1983

Filed:

Apr 14, 1981

Appl. No.:

6/254226

Inventors:

Robert H. Craemer - Cherry Hill NJ
A. Brent Woolston - Palmyra NJ

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B26D 536
G06F 1520

US Classification:

364475

Abstract:

At a transition between first and second sets of index marks on a web, a target is applied adjacent the initial mark of the second set. The target is sensed and as a result the web is severed transversely at the transition between the sets of marks. A gap is formed in the web. A microcomputer synchronizes a cut-off machine with the second set of marks while the cut-off machine is in the gap whereby operator intervention is eliminated and scrap minimized.

Appl. No.:

6/245299

Inventors:

Robert H. Craemer - Cherry Hill NJ
Anthony N. Scardapane - Pennsauken NJ

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B05C 108
B05D 128

US Classification:

427 8

Abstract:

The caliper of single face corrugated paperboard is measured and a caliper signal is generated. A gap signal is generated to represent the gap between a rider roll and an applicator roll. A value is subtracted from the caliper signal or a value is added to the gap signal to represent the desired compression of the paperboard as it passes between the rider roll and the applicator roll. A comparator compares the signals after one of the signals has been modified and generates a difference signal. A motor responsive to the difference signal is provided for adjusting the rider roll so as to maintain the gap at a preselected value with respect to the caliper of the board prior to its compression.

Inventors:

Robert H. Craemer - Cherry Hill NJ

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

G06F 1546
G05D 500

US Classification:

364471

Abstract:

Proximity type sensors detect the passage of the flutes of a single face web at the inlet and outlet of a bridge. Separate counts are maintained of the number of flutes detected at the bridge inlet and outlet based on the outputs of the sensors. Data representative of the number of flutes per unit length of one or more single face webs is stored in memory. The appropriate data is selectively retrieved from memory and multiplied by the difference between the flute counts at the bridge inlet and outlet to obtain a signal representative of actual length of web on the bridge.

Appl. No.:

6/831211

Inventors:

Robert H. Craemer - Cherry Hill NJ

Assignee:

Molins Machine Company - Cherry Hill NJ

International Classification:

B41F 1324

US Classification:

101426

Abstract:

The shafts of the sections of a printer-slotter machine are gear coupled and are set to the desired phase relation by a microcomputer control while coupled. The sections need not be de-coupled during set up. During normal operation, following set up, the section shafts are mechanically locked in phase register.

Appl. No.:

5/903350

Inventors:

Robert H. Craemer - Cherry Hill NJ
Donald J. Evans - Cherry Hill NJ

Assignee:

Molins Machine Company, Inc. - Cherry Hill NJ

International Classification:

B31F 120
B65G 3700
B65G 4310

US Classification:

156205

Abstract:

A paperboard web is severed transversely between the double facer machine and the slitter-scorer after the completion of a production order. The speed of the double facer machine is maintained constant while the severed web section is accelerated to a speed substantially above the speed of the double facer machine to create a gap. Adjustments to one or more of the slitter-scorer and cut-off for the next production order are made while the same are in the gap. Sheets cut from the web section are shingled on a shingling conveyor. The speed of the shingling conveyor is accelerated prior to the arrival of the last sheet of the web section and decelerated while the gap is on the shingling conveyor.
