Abstract

This machine is a high-speed laminating machine for laminating a narrow strip of magnetic tape onto a wider paper strip. The resulting composite strip can thereafter be cut into short lengths and further processed to manufacture identification cards, credit cards, rapid transit tickets and the like having identifying numbers and other data magnetically encoded onto the magnetic strips.

Laminating Machine

       This machine is a high-speed laminating machine for
laminating a narrow strip of magnetic tape onto a wider paper strip.
The resulting composite strip can thereafter be cut into short
lengths and further processed to manufacture identification cards,
credit cards, rapid transit tickets and the like having identifying
numbers and other data magnetically encoded onto the magnetic strips.

      Fig. 1 shows a plan view and Fig. 2 shows a schematic
cross-sectional elevational view of the laminating machine. The paper
strip material 10 is fed from a second supply spool 11, while the
magnetic tape 12 is fed from a second supply spool 13.  Before
merging with the magnetic tape 12, the paper strip 10 passes beneath
a bank of infrared heater lamps 14 which heat the paper to the proper
lamination temperature.  An infrared temperature sensor 15 senses the
paper temperature as it emerges from under the final heater lamp 14
and the output signal from the sensor 15 is fed to a control system
which regulates the electrical power supplied to the heater lamps 14
so as to prevent overheating of the paper strip 10.  The magnetic
tape 12 is a mylar mag netic tape which is comprised of a strip of
mylar film having magnetic oxide material deposited on one side
thereof.  The magnetic tape 12 is laminated onto the paper strip 10
by simultaneously passing both strips between a pair of laminating
rollers 16 and 17.  These rollers 16 and 17 press the magnetic tape
12 against and laminate it into the paper strip 10.  The oxide
coating side of the tape 12 is the side that is pressed against the
paper strip 10.

      The laminating roller 16 is actually a dual-purpose laminating
and calendering roller and is provided with an internal radiant
heating mechanism.  The construction of this internal radiant heating
mechanism is shown in more detail in Fig....
