Ultrasonic Seaming Of Abutting Strips For Paper Machine Clothing
US Patent:
5713399, Feb 3, 1998
Filed:
Feb 7, 1997
Appl. No.:
8/797560

Assignee:
Albany International Corp. - Albany NY
International Classification:
D03D 1300
US Classification:
139383AA
Abstract:
A method for manufacturing a papermaker's fabric by spirally winding a woven fabric strip, narrower than the intended width of the fabric, and the papermaker's fabric manufactured in accordance with the method, are disclosed. The fabric strip includes lengthwise and crosswise yarns, and has a lateral fringe along at least one lateral edge thereof, the lateral fringe being unbound ends of the crosswise yarns extending beyond the lateral edge. During the spiral winding of the fringed strip, the lateral fringe of a turn overlies or underlies an adjacent turn of the strip. The lateral edges of adjacent turns abut against one another. The spirally continuous seam so obtained is closed by ultrasonically welding or bonding the overlying or underlying lateral fringe to the fabric strip in an adjacent turn.
Composite Waterproof And Flame Resistant Fabrics
US Patent:
4302496, Nov 24, 1981
Filed:
Oct 21, 1980
Appl. No.:
6/199270
Inventors:
James G. Donovan - Norwell MA
Assignee:
Albany International Corp. - Albany NY
International Classification:
B32B 300
US Classification:
428196
Abstract:
A composite waterproof fabric for tent walls and the like which is suitable for use under severe service conditions, and which is opaque, of light weight and flame or fire resistant. The fabric comprises at least three plies, namely outer and inner woven, flame resistant plies and a middle ply of polytetrafluoroethylene which is hydrophobic, microporous and moisture vapor permeable. Tensile strength and tear resistance are imparted to the composite fabric largely by the inner ply, and abrasion protection is imparted by the outer ply. A light weight fabric of this construction is opaque, color adaptable and flexible at very low ambient temperatures.

Abstract:
A method whereby a water permeable press fabric is given greater dewatering and drainage capacity by providing voids which are reservoirs of minimum pressure available to accept water.
Method For Joining Nonwoven Mesh Products
US Patent:
6240608, Jun 5, 2001
Filed:
Apr 12, 1999
Appl. No.:
9/290899
Inventors:
Maurice R. Paquin - Averill Park NY
James G. Donovan - Norwell MA
James G. Donovan - Norwell MA
Assignee:
Albany International Corp. - Albany NY
International Classification:
D04H 1300, B32B 506
US Classification:
28142
Abstract:
A press fabric for the press section of a paper machine has a base fabric which includes a nonwoven mesh fabric. The base fabric, or a layer thereof, is assembled in integral form using a strip or strips of the nonwoven mesh fabric. The assembly may be effected by spirally winding the nonwoven mesh fabric in a plurality of non-overlapping turns, by abutting each turn of the nonwoven mesh fabric against that previously wound, and by joining each turn of the nonwoven mesh fabric to that previously wound to form an endless loop. Alternatively, a plurality of endless loops of equivalent length are formed from separate strips of nonwoven mesh fabric, and arranged in a side-by-side abutting relationship. The endless loops are then joined, one to the next, to provide a base fabric, or component thereof, in the form of an endless loop.

Assignee:
Albany International Corp. - Albany NY
International Classification:
B32B 506, D02G 300
US Classification:
428296
Abstract:
This invention relates to synthetic fiber thermal insulator material in the form of a cohesive fiber structure, which structure comprises an assemblage of:
(a) from 70 to 95 weight percent of synthetic polymeric microfibers having a diameter of from 3 to 12 microns; and
(b) from 5 to 30 weight percent of synthetic polymeric macrofibers having a diameter of 12 to 50 microns,
characterized in that at least some of the fibers are bonded at their contact points, the bonding being such that the density of the resultant structure is within the range 3 to 16 kg/m. sup. 3, the thermal insulating properties of the bonded assemblage being equal to or not substantially less than the thermal insulating properties of a comparable unbonded assemblage. The invention also relates to the method of preparing said material.
