Abstract

A method of pulling yarn from a plurality of bobbins 1 mounted on a creel, includes mounting a plurality of bobbins side by side in a row and locating adjacent a first bobbin a guide eye or tube 6 for guiding yarn from another bobbin in the row, preferably the adjacent bobbin in the row. The tubes 6 or eyes are mounted on arms 5 which in addition to receiving the tubes are formed with slots to accommodate the traversing movement of yarn coming off the bobbins adjacent the respective arms.

Description

2361249 CREEL The present invention relates to a creel and to a method of

guiding yarn from yarn packages mounted on a creel.

C Yarn packages used in textile machines are frequently stored in a creel.

In some creels, such as in carpet weaving, the yam package is in the form of a bobbin, and the yam is pulled off from its side, causing the bobbin to rotate. The creel normally carries a large number of bobbins and in order io to prevent different yarns tangling, they are often guided through tubes, or eyes close to the bobbins.

It is important to keep the yam tension low. However, since the guide eye or tube is located close to the bobbin, normally at a central location relative to the length of the bobbin, yam tension is increased when the yarn is pulled off the bobbin adjacent to one of its ends.

A general object of the present invention is to provide a creel which enables yarn to be pulled off bobbins mounted on the creel with minimum tension.

According to one aspect of the present invention there is provided a method of pulling yarn from a plurality of bobbins mounted on a creel, the method including mounting a plurality of bobbins side by side in a row and locating adjacent a first bobbin a guide eye or tube for guiding yarn from another bobbin in the row, preferably the adjacent bobbin in the row.

According to another aspect of the invention there is provided a creel including at least one row of bobbin mounting means, the bobbin 1 mounting means being spaced from one another, a yarn guide assembly associated with each bobbin mounting means, the yarn guide assembly including a first and second yarn guides, the first yarn guides preferably being in the form of a guide eye or tube for receiving a first yarn from a bobbin mounted on another bobbin mounting means in said row, the second yarn guide being adapted to receive a second yarn from the bobbin mounted on its associated bobbin mounting means, the second yarn guide permitting said second yarn to translate to and fro as it is drawn from said bobbin mounted on the associated bobbin mounting means.

Preferably each yarn guide assembly includes a body, the second yarn guide preferably being a slot formed in the body.

Figure 1 is a side view of a small section of creel according to a 15 first embodiment of the invention; Figure 2 is a plan view of the creel shown in Figure 1; Figure 3 is an end view of the creel shown in Figure 1; Figure 4 is a side view of a small section of creel according to a second embodiment of the invention; Figure 5 is a plan view of the creel shown in Figure 4; Figure 6 is an end view of the creel shown in Figure 4.

Referring initially to Figures 1 to 3 there is shown a first embodiment 50 which utilises guide tubes 6 for guiding yarn.

The creel 30 includes a row of main frame members 40 on each of which are mounted bobbin mounting means 41, preferably in the form of a shaft 42 secured to frame member 40.

Associated with each bobbin mounting means 41 is a yarn guide assembly 45, preferably in the form of an arm 5.

1.

The arm 5 includes a first yarn guide in the form of a tube 6 and a second yam guide 43 in the form of a slot 3. The arm 5 is also provided with a slot 11 through which a tube 6 extends toward a neighbouring arm 5.

Each yarn FY is fed from a bobbin 1 through slot 3 of the associated bobbin mounting means 41 to the tube 6 associated with the next bobbin Since the tube 6 is not located at a close distance from the bobbin 1 from which the first yarn FY is drawn, the angle of travel between that bobbin and the tube 6 is not sharp, ie. it is relatively shallow, even when the yarn 15 FY is located at the longitudinal ends of the bobbin 1.

It will be appreciated that as yarn FY is being pulled off its bobbin 1, the yarn FY translates to and fro as it travels between the ends of the bobbin. Since the second yarn guide 43 is in the form of a slot 3, such translatory 20 movement of the FY yarn is permitted.

The first guide 6 of one arm 5 and the second guide 3 of the neighbouring arm 5 serves to keep the section of yarn FY located therebetween free of the intermediate bobbin 1.

A projection may be added to the end of the arm 5 on which spare bobbins may be stored before changing over.

In Figures 4 to 6, a second embodiment 60 is illustrated. The second embodiment 60 is similar to the first embodiment except that the guide 3 tubes 6 have been dispensed with and replaced by guide eyes 22. Accordingly a yarn FY passes through the slot 3, through the guide eye 22, and over the top edge of the arm 5. The yarns 21, 25 and 26 are guided at the front of the creel in such a way that they are kept apart as shown. This means that the yarns never rub over each other, avoiding the possibility that one yarn can drag another one along with it.

Claims

1. A method of pulling yarn from a plurality of bobbins mounted on a creel, the method including mounting a plurality of bobbins side by side in a row and locating adjacent a first bobbin a guide eye or tube for guiding yarn from another bobbin in the row, preferably the adjacent bobbin in the row.

2. A creel including at least one row of bobbin mounting means, the io bobbin mounting means being spaced from one another, a yarn guide assembly associated with each bobbin mounting means, the yarn guide assembly including a first and second yarn guides, the first yarn guides preferably being in the form of a guide eye or tube for receiving a first yarn from a bobbin mounted on another bobbin mounting means in said row, the second yarn guide being adapted to receive a second yarn from the bobbin mounted on its associated bobbin mounting means, the second yarn guide permitting said second yarn to translate to and fro as it is drawn from said bobbin mounted on the associated bobbin mounting means.

3. A creel according to Claim 2 wherein each yarn guide assembly includes a body, the second yarn guide being a slot formed in the body.

4. A creel substantially as herein described with reference to and as 25 illustrated in the accompanying drawings.

5. A method of pulling yarn from a plurality of bobbins mounted on a creel substantially as herein described with reference to the accompanying drawings.
