Pressure laminator apparatus and non woven fabric formed thereby

A pressure lamination apparatus, comprising:

• a frame, two counter rotating upper and lower drive belts rotatably mounted in the frame and adapted to be movable in a same direction into said inlet of the lamination section and out of said outlet of the lamination section wherein the drive belts are adapted for receiving a substrate material therebetween for treatment within the lamination section,
• a pressure box mounted in the frame, said pressure box further comprising, spaced apart upper and lower plattens forming a space therebetween defining a lamination section having an inlet and an outlet for receiving the counter rotating upper and lower drive belts,
• a compressed air generator for supplying pressure within the space of the laminator section,
• at least one pressure seal mounted in the upper platten, said pressure seal contacting the upper drive belt so as to contain said pressure within said lamination section thereby compressing said upper belt and said lower belt against said substrate material.

A pressure lamination apparatus, including:

• a frame;
• a pressure box mounted in the frame, comprising spaced apart upper and lower sections forming a space therebetween defining a lamination section;
• two counter rotating upper and lower drive belts, rotatably mounted in the frame and adapted to be movable in the same direction through the space between the upper and lower sections of the pressure box, whereby in accordance with the direction of movement of the belts, one end of the pressure box acts as an inlet for a substrate material to be treated and an opposite end acts at as an outlet for the treated substrate material;
• and
• a fluid medium pressure generator for supplying pressure to the upper and lower sections of the pressure box for compressing the drive belts moving therebetween, wherein the upper pressure box section comprises a pressure seal and wherein the pressure seal comprises at least one rubber bladder.
