Abstract

A process for creating multiple tufts for a tufted article comprises directing the initial filament bundle into a first channel, causing the bundle to move through the first channel while splitting the bundle into a plurality of tufts according to a predetermined pattern, and directing the plurality of tufts into the plurality of second channels such that each of the plurality of tufts has its own second channel. An apparatus comprises a first plate having a first channel for receiving a filament bundle, a splitting element for separating the bundle into the plurality of individual tufts, a second plate having a plurality of second channels for receiving the plurality of tufts, and a driving means for moving the filaments in the channels.

First claim

What is claimed is:

1. A process for creating multiple tufts for a tufted article, the process comprising:
providing an initial filament bundle comprising a first plurality of individual filaments;
directing the initial filament bundle into a first channel;
pushing the initial filament bundle by a pin abutting a free end of the initial filament bundle inside the first channel, thereby causing the initial filament bundle to move through the first channel in a direction substantially parallel to a longitudinal direction of the initial filament bundle;
splitting the initial filament bundle into a plurality of tufts according to a predetermined pattern, each tuft comprising a second plurality of individual filaments;
wherein splitting the initial filament bundle into a plurality of tufts according to a predetermined pattern comprises driving an opposite end of the free end of the initial filament bundle through a splitting element that separates the initial filament bundle into the plurality of individual tufts according to a predetermined pattern; and

directing the plurality of tufts into a plurality of second channels such that each of the plurality of tufts moves through its own second channel defining a shape of the tuft moving therethrough in a direction substantially parallel to a longitudinal axis of the channel.

2. The process of claim 1 , wherein directing the initial filament bundle into a first channel comprises causing the initial filament bundle to move through the first channel disposed in a first plate towards a second plate having the plurality of second channels therein.

3. The process of claim 1 , wherein splitting the initial filament bundle into a plurality of tufts according to a predetermined pattern comprises splitting the initial filament bundle into at least two tufts.

4. The process of claim 1 , wherein splitting the initial filament bundle into a plurality of tufts according to a predetermined pattern comprises splitting the initial filament bundle into at least a first tuft and a second tuft, wherein said at least first and second tufts differ from one another in at least one parameter selected from the group consisting of an equivalent diameter, a number of individual filaments, and a cross-sectional shape.

5. The process of claim 1 , wherein splitting the initial filament bundle into a plurality of tufts according to a predetermined pattern occurs gradually with respect to a thickness of the initial filament bundle.
