Abstract
Abstract Tubing is formed by glass fibers wound around and bonded together on a motor driven mandrel. The fibers can be wound in a honeycomb pattern having overlapping turns by a reciprocating guide carriage. The carriage includes a support reciprocated parallel to the mandrel axis by an endless belt driven in alternate directions by a fist motor. The support carries the fiber guide also reciprocable by an endless belt driven in alternate directions by a second motor. A plurality of cams operate associated variable resistors to control the first and second motors and thereby the relative position of the carriage and the guide on the carriage with respect to the mandrel.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A machine for making tubular members comprising a mandrel driven in rotation, a carriage for feeding thread, means for moving said carriage parallel to the axis of rotation of said mandrel in a constant direction, a thread-guiding device mounted on said carriage to slide parallel to said axis, driving means imparting a reciprocating motion to said guiding device with a frequency slightly different than the number of revolutions per second of the mandrel whereby the thread is wound according to a honeycomb pattern and a helical layer of thread having overlapping turns is formed, first cam means, means for drivinG said first cam means in synchronism with said carriage for controlling the movements of said carriage, second cam means, and means for driving said second cam means in synchronism with said carriage for controlling the reciprocating movements of said guiding device.
Claim 2
Dependent Claim
141 words
A machine for making tubular members comprising a mandrel driven in rotation, a carriage for feeding thread, means for moving said carriage parallel to the axis of rotation of said mandrel in a constant direction, a thread-guiding device mounted on said carriage to slide parallel to said axis, driving means imparting a reciprocating motion to said guiding device with a frequency slightly different than the number of revolutions per second of the mandrel whereby the thread is wound according to a honeycomb pattern and a helical layer of thread having overlapping turns is formed, first cam means, means for drivinG said first cam means in synchronism with said carriage for controlling the movements of said carriage, second cam means, and means for driving said second cam means in synchronism with said carriage for controlling the reciprocating movements of said guiding device.
Claim 3
Dependent Claim
45 words
A machine according to claim 1 wherein variable resistances responsive to the position of said guiding device are mounted on the latter and cooperate with other variable resistances responsive to said second cam means to control the movements of said guiding device on said carriage.
