A method of potting in a single or multi-cavity mold a plurality of fibers in continuous tow form to encapsulate the fibers, fill the interstices and form a solid tubesheet of selected shape and length. After transversely cutting through the thus formed tubesheet and the fibers therein a pair of tubesheets are formed each attached to and forming the end portion of a length of fibers. Potting at spaced longitudinal locations on the continuous tow, and transverse cutting, produces fiber bundle assemblies having a length of the tow of hollow fibers between a pair of axially spaced tubesheets. The process is semi-continuous or continuous, as desired.

A method for forming a tubesheet encapsulating a multiplicity of fibers in linearly arranged continuous tow form which comprises the steps of (1) positioning a tow of fibers in a mold, said tow comprising a multiplicity of linearly arranged fibers, (2) flowing a polymeric composition into said mold

A method for forming a tubesheet encapsulating a multiplicity of fibers in linearly arranged continuous tow form which comprises the steps of (1) positioning a tow of fibers in a mold, said tow comprising a multiplicity of linearly arranged fibers, (2) flowing a polymeric composition into said mold and through the interstices between said fibers in a direction substantially at a right angle to the longitudinal axis of said linearly arranged fibers and in a quantity and for a time sufficient to fill the interstices between said fibers and to fill said mold, (3) causing said polymeric composition to solidify adjacent to the axial ends of said mold while said polymeric composition continues to flow across said fibers and to solidify and encapsulate said fibers therein to thereby form a tubesheet having the external configuration of the cavity of said mold, and (4) removing said tubesheet from said mold.
