    • A gasket is provided for creating a seal between two surfaces. The gasket may include a pervious base sheet and a permeating material applied to or incorporated into the base sheet. The gasket is formed by various methods disclosed herein. The gasket may include a base sheet, a primary sealing material covering and/or impregnated the base sheet, and a secondary sealing material covering the primary sealing material. The secondary material may be applied in a predetermined pattern of raised and lowered sections or may be applied as a bead of sealing material. The secondary material may be applied through a variety of techniques including jetting and dispensing using robots such that beads with custom engineered and changing configurations along their lengths are possible. These custom engineered sealing beads provide optimum sealability over the entire area of a joint to be sealed.
    • 提供垫圈以在两个表面之间形成密封。 衬垫可以包括渗透的基片和施加到基底片上或结合到基片中的渗透材料。 垫圈由本文公开的各种方法形成。 衬垫可以包括基片,覆盖和/或浸渍基片的主密封材料和覆盖主密封材料的次密封材料。 辅助材料可以以预定图案的升高和降低部分施加,或者可以作为密封材料的珠粒施加。 二次材料可以通过各种技术来施加,包括使用机器人的喷射和分配,使得沿其长度具有定制设计和改变构型的珠粒是可能的。 这些定制设计的密封珠在要密封的接头的整个区域上提供最佳的密封性。
