Abstract:
An apparatus for making an air and moisture barrier laminate assembly for sealing the interface between a sill plate and a foundation wall, said apparatus comprising:first and second rollers positioned in a parallel opposed relationship to one another to define an inlet nip and an outlet nip, said rollers operative to rotate in a cooperative manner; means for controllably turning at least one of said rollers; a first holder for holding a length of a first membrane having a surface adapted for securement to a foundation wall, said holder operative to hold said first membrane in a first position relative to said inlet nip; a second holder for holding a length of a spacer material of a predetermined thickness, said holder holding said spacer material in a second position relative to said inlet nip; a third holder for holding a length of a second membrane having a surface adapted for securement to a sill plate, said holder operative to hold said second membrane in a third position relative to said inlet nip; and said first and second rollers further operative to simultaneously receive and contact said first membrane, said spacer material and said second membrane at said inlet nip in a known spaced relationship and apply a predetermined compressive force thereto.
