ABSTRACT:
The present invention entails a method and apparatus for automatically glue-bonding scrim to a non-woven fiber mat. The fiber mat and scrim are both conveyed or advanced towards a pair of compression rollers. Prior to reaching the compression rollers, a series of glue guns direct a spray of glue onto one side of either the fiber mat or the scrim. Thereafter, the fiber mat and scrim are fed through the pair of compression rollers that press the scrim and fiber mat together to form a bonded fiber mat-scrim composite. From the compression rollers, the final formed fiber mat-scrim composite is conveyed to a take-up station where the composite is overlapped or wound into a roll.
