Composite fibrous writing instrument elements and their manufacture

Abstract

Abstract A CONTINUOUS PROCESS INVOLVING THE COMPRESSION AND BONDING TOGETHER, INDUCED BY HEAT, OF VIRTUALLY PARALLEL STRANDS OF FILAMENTARY MATERIAL, FOLLOWED BY THE ADDITION OF FURTHER STRANDS OF FILAMENTARY MATERIAL TO THE EXTERIOR SURFACE OF THE PREVIOUSLY BONDED STRANDS AND FURTHER COMPRESSION AND BONDING, WHEREBY THE STRENGTH, ABILITY TO CONVEY LIQUIDS BY CAPILLARITY AND OTHER CHARACTERISTICS OF THE CONTINUOUS, POROUS, ABSORBENT, ELONGAGED ULTIMATE OBJECT ARE CONTROLLED. TWO OR MORE SEQUENTIALLY COMPRESSION AND HEAT-SETTING OR BONDING STEPS MAY BE EMPLOYED. VARIOUS FIBROUS OR FILAMENTARY MATERIALS MAY BE USED AND THEIR PROPERTIES UTILIZED TO BEST ADVANTAGE, STRENGTH AND RESISTANCE TO LOAD MAY BE IMPARTED TO A MINUTE AXIAL PORTION OF A WRITING POINT WITHOUT IMPAIRMENT OF NECESSARY CAPILLARY CHARACTERISTICS IN OTHER AREAS OF THE POINT. PRODUCTS HAVING SUCH CONTROLLED CHARACTERISTICS FOR USE AS RESERVOIR FILLERS AND WRITING POINTS IN WRITING INSTRUMENTS AND HAVING DESIRED CAPILLARY RELATIONSHIPS THEREBETWEEN AS WELL AS LOAD-BEARING PROPERTIES. WRITING INSTRUMENTS PROVIDED WITH PRODUCTS OF THIS INVENTION.
