Abstract

ABSTRACT OF THE DISCLOSURE

The present invention provides a belt and method of making same formed from single strips of inner and outer belting material folded upon themselves to provide identical characteristics at both the front and back sides of the belt.

Description

~3~
FIELD OF THE INVENTION

1 The present invention relates to a double thickness belt and in particular a cloth belt having substantially identical front and back side surfaces.

BACKGROUND OF THE INVENTION

The standard construction for a cloth belt is to make the belt wi-th characteristics which differ from the front to the back of the belt. For instance, the most widely available cloth belt is formed using a cloth material at the front side of the belt and a relatively inexpensive plastic material at the back or hidden side of the belt.

Unfortunately, when using dissimilar materials the belt often does not have a high quality appearance and may be subject to problems such as crimping where the backing material does not have the same flex properties as the cloth front side of the belt.

SUMMARY OF THE PRESENT INVENTION

The present invention provides a belt in which the front and back sides are made of identical construction overcoming the drawbacks discussed above. More particularly, the present invention provides a belt having front and back sides formed from single strips of inner and outer material both pieces doubled upon themselves and presenting a single fold at a first edge region and pair of folds at a second edge region of the belt. The belt is then secured at the second edge region to hold the front and back sides -together with one another.

~23~2~2 1 The belt of the present invention due to its corresponding construction at both the front and back sides or faces not only has an extremely appealing appearance but in addition has durability qualities not found in presently available two piece standard belt constructions.

BRIEF DISCUSSION_OF THE DRAWINGS

The above as well as other advantages and features of the present invention will be described in greater detail according to the preferred embodiments of the present invention in which;

Figures 1 and 2 are perspective and cross-sectional views respectively of a standard prior art two piece belt construction.

Figure 3 is a perspective view of a section of a belt according to a preferred embodiment of the present invention.

Figure 4 is an end view of the belt construction of Figure 3 and Figures 5 through 7 show various assembly steps in arriving at the belt construction of Figure 3.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED EMBODIMENTS OF
THE PRESENT INVENTION

The prior art belt shown in Figures 1 and 2 shows a construction generally used in making cloth belts. This construction comprises a forward cloth surface 1 and a 3~ 2 1 plastic or paper like rear surface 5. The cloth wraps around as indicated at 3 onto the rear surface 5 where the two pieces are stitched together as indicated at 7.

Figure 3 shows a belt construction which is particularly applicable to a cloth belt in accordance with the present invention. In this construction the belt has a forward cloth surface 13 as well as a rearward cloth surface 15 both of which have identical inner liners giving the belt both a uniform appearance and a consistent flex characteristic which substantially enhances the life of the belt.

Before dealing with the entire belt construction reference is had to, figures 5 through 8, showing the assembly of the belt. The initial components used in the belts formation are a single strip of cloth material 12 and a strip of interior lining material 22. In the preferred form this lining is of a felt like material which is readily deformable without creasing as is the outer cloth material used in forming the belt.

As seen in Figure 6 lining 22 is laid over the inner surface of cloth strip 12 and the cloth strip being wider than the lining presents margins or edge regions 18 and 20 to either side of the lining. At this point an adhesive is applied over the entire arrangement so as to cover both the lining and the outer margins.

The next stage in the formation of the belt is to fold the margins 18 and 20 onto the adhesive bearing edge surface of liner 22 to provide a pair of folds 19 and 21 as seen in Figure 7. These folds are maintained in their secured positions 3~

1 because of the adhesive binding indicated at 27 and 29 respectively between the margins and the lining. Also, it should be noted that some of the adhesive due to the porous nature of the lining will seep through to the cloth fabric to provide a further binding between the lining and the cloth to the opposite side from the folds. However, the amount of glue applied relative to the porousity of the liner is such that there is no heavy flow of adhesive through the lining which might otherwise rnark the cloth strip.

From the Figure 7 position the now assembled cloth strip and inner lining are folded as shown in Figure 8 to provide a single fold 17 at one edge surface of the shaped belt with folds 19 and 21 aligning side by side with one another at the other edge surface of the belt. At the center of the belt, between its forward and rearward surfaces, the inner lining adheres to itself to hold the belt in a position which then allows it to be stitched as indicated at 31 in Figure 3 to hold it in its assembled form. Additional sti-tching 33 is provided at the other edge surface to give the belt a finished look.

In the completed version of the belt the two folds 19 and 21 are held so tightly against one another that without a detailed examination of the belt they appear to present a single fold edge consistent with fold 17 at the other edge of the belt.

When the belt is fully constructed, as shown in Figure 3, it comprises forward and rearward fabric surfaces 13 and 15 respectively with forward and rearward inner lining surfaces 23 and 25 adding body to the belt.

1 It will now be seen from the description above how a belt constructed in accordance with the present invention is made from a simple yet extremely efficient method to produce identical surfaces at both the front and back sides of the belt adding both to its appearance and to its durability. In addition, although various preferred embodiments have been described herein in detail, it will be appreciated that variations may be made without departing from the spirit of the invention or the scope of the appended claims.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A belt having front and back sides formed from a first single strip of material doubled upon itself and presenting a single fold at a first edge and a pair of folds at a second edge thereof, said belt being secured at said second edge to hold said front and back sides together with one another and a second single strip of fabric material also folded upon itself interiorly of said first strip of material and secured thereto at said pair of folds of said second edge of said belt.

2. A belt, as claimed in Claim 1, wherein said first strip of material comprises a cloth fabric.

3. A belt, as claimed in Claim 2, wherein said second strip of material comprises a non-woven felt fabric.

4. A belt, as claimed in Claim 1, including an adhesive on said second strip of material folded upon itself to assist in holding said front and back sides of said belt together with one another.

5. A belt, as claimed in Claim 4, wherein said second strip of material is somewhat porous to allow some penetration of said adhesive to said first strip of material.

6. A belt, as claimed in Claim 4, wherein said first strip of material is wider than said second strip of material and wherein said adhesive extends into said pair of folds for securing said pair of folds overlapping and adhesively securing said second strip of material.

7. A method of making a belt having corresponding fabric material outer and inner surfaces comprising folding a single strip of the fabric material upon itself to provide a first single fold at one edge region and a pair of free material edges at the other edge region of the folded strip, folding the free material edges inwardly upon themselves to provide side by side second folds and securing the side by side second folds to one another, said method further including fitting a fabric lining of smaller width onto said strip of fabric which then presents uncovered fabric margins to either side of said lining, applying an adhesive to said lining and uncovered margins, folding said margins to partially overlap and adhere to said lining and then folding said strip and lining which adheres to itself to shape said belt.

8. A method, as claimed in Claim 7, including stitching said side by side folds to one another.

9. A method, as claimed in Claim 8, including additionally stitching along said first single fold.
