Method and apparatus for making articles having bristles

Abstract

Methods and apparatus for making elongated articles are disclosed. One method includes feeding at least one base string along an axis, wrapping at least one monofilament around the axis to produce a number of monofilament wraps per length of base string which are transported by the base string, bonding the wraps to the base string with ultrasonic energy, and cutting the wraps at a point downstream of where the wraps are bonded to the base string. The result is an article having two rows of monofilament segments connected to the base string.

1 . A method for making an elongated article comprising the steps of: 
 feeding at least one base string along an axis;    wrapping at least one monofilament around the axis to produce a number of monofilament wraps per length of base string which are transported by the base string;    bonding the wraps to the base string; and    cutting the wraps at a point downstream of where the wraps are bonded to the base string to thereby form an article having two rows of monofilament segments connected to the base string.    
     
     
         2 . A method for making an elongated article comprising the steps of: 
 feeding a base string along a first support;    wrapping at least one monofilament around a second support to form a plurality of loops;    feeding the loops transversely over the at least one base string;    pressing the loops into contact with the base string, whereby the loops are transported by and with the at least one base string; and    bonding the wraps to the base string to form an article having two rows of monofilament loops connected to the base string.
