Abstract
The method consists in pressure bonding a first strip to a second strip through a bonding press, marking each of the strips with the pattern pitches and juxtaposing the pattern pitch markings of each strip at the time of the bonding by extension of at least one strip with respect to another and by differential heating of each of the opposing strips to cause a relative shift, by expansion, of the two strips with respect to each other.

Method for the continuous assembly of patterned strips, one of which is a pre-slotted metal strip and the other a pre-perforated insulator strip, comprising providing each of the strips with reference marks, continuously unwinding the strips from respective feeder rollers, continuously transporting the strips through a bonding press under tension, sensing the locations of said reference marks, pressure bonding the first strip to the second strip through the bonding press, and, in response to said sensing step, juxtaposing the reference marks of each strip at the time of the bonding by at least one of (1) varying the tension applied to at least one of said strips so as to extend one strip with respect to the other, and (2) differentially heating each of the opposing strips to cause a relative shift, by expansion, of the two strips with respect to each other.
A method for the continuous assembly of patterned strips including a first, pre-slotted metal strip and a second, pre-perforated insulator strip, said first and second strips having different coefficients of expansion, said method including:
- (A) providing said first and second strips with reference marks;
- (B) continuously unwinding said first and second strips from respective feeder rollers;
- then
- (C) continuously transporting said strips through a bonding press;
- (D) pressure bonding said first strip to said second strip in said bonding press during said transporting step;
- (E) sensing the locations of the reference marks;
- and
- (F) in response to said sensing step, juxtaposing the reference marks of each strip at the time of the bonding by differentially heating said strips to cause a relative shift, by expansion, of the two strips with respect to each other.
Device for the continuous assembly of patterned strips, one of which is a pre-slotted metal strip and the other is a pre-perforated insulator strip, each of said strips having reference marks, said device comprising:
- (A) strip feeding means including (1) a first strip unwinder on which is mounted the metal strip wound on itself, (2) a second strip unwinder on which is mounted the insulator strip wound on itself, and (3) means for continuously transporting both strips to and through a press located downstream of the unwinders, (B) means for sensing me positions of said reference marks, (C) means, responsive to said means for sensing, for juxtaposing the reference marks of said strips by adjusting the tension on at least one of said strips to thereby extend one strip with respect to the other, and (D) means, responsive to said means for sensing, for juxtaposing the reference marks of said strips by differentially heating each of the opposing strips to obtain a relative shift, by expansion, of the two strips in relation to each other.
