Abstract
A method of pressure bonding composite material comprises passing a pair of strips through a nip defined between a pair of abutting rolls. At least one of a composite material which is pressure bonded as a result of passage through the nip and one of the strips which are to be introduced into the nip is wrapped around an associated roll. While the composite material or the strip is so disposed, the pair of rolls are driven at differential peripheral speeds, thereby controlling the draft of each strip.
Claims8
A method of pressure bonding composite material comprising passing a pair of strips through a nip defined between a pair of counterrotating abutting rolls and therewith bonding them together under pressure into a composite material strip, wherein the improvement comprises the steps of
- wrapping at least one of the following:
- (1) the composite strip, which has passed through the nip, around one of said pair of abutting rolls, and
- (2) one of said pair of strips, which is to be introduced into said nip, around the other of said pair of abutting rolls;
- and
- simultaneously driving said abutting pair of rolls at different peripheral speeds.
A method of pressure bonding composite material comprising passing a pair of strips through a nip defined between a pair of counterrotating abutting rolls and therewith pressure bonding them together under pressure into a composite material strip, wherein the improvement comprises wrapping one of said pair of strps, to be introduced into the nip, around one of said abutting rolls under a given pressure, causing the other of said pair of strips and said composite material strip to pass through the nip without any substantial wrapping thereof around either said roll, and driving said pair of rolls at differential peripheral speeds while said strips pass through the nip.
