Method and Apparatus to Make Decorative Fastenings for Carrier Bags Containing Gifts, Easy to Apply and of Pleasing Appearance

Abstract

A device for fastening bags has a length of adhesive tape with a decorative object fixed to one or both ends of the length of tape. The device is produced in series by an apparatus having: actuators for linear and angular feed, a pair of pneumatic pincers, a cutter, a reel to carry the roll of adhesive tape, a stitching device and a dispenser of the decorative pompom. A microprocessor controls the apparatus for cyclical execution of the method wherein: the pincers engage the end of the tape through a cutter and pull the tape for a previously set length to bring it between the stitching device and a first pompom. The cutter then cuts the tape. The pompon is stitched to the non-glued surface and the pincers pull the tape for an equal length so as to bring its other end between the stitching device and a second pompon which is then stitched onto the tape. The pincers rotate and open to expel the finished product.

Description

FIELD OF APPLICATION[0001]The present invention relates to decorative products in general, and in particular to a method and to an apparatus for making decorative fastenings for bags enclosing gifts, fastenings that are easy to apply and pleasing to look at.PRESENT STATE OF THE ART[0002]A tendency at present in vogue is to use carrier-type bags of paper, of woven or non-woven fabrics, or of plastic material for containing gifts rather than the former types of packaging with paper and string . FIG. 1A shows a short strip of semi-transparent adhesive tape, often called sticky tape, to hold together the top edges of such bags, also known as shoppers. FIGS. 1B and 1C show front and side perspective views of these bags fastened by the adhesive tape in FIG. 1A.[0003]Because of its parallel edges, the bag can be suitably fastened with adhesive tape, labels, clips or pegs, apart from the handles with which it is supplied. These fastening methods match the edges together by mechanical action...

AI Technical Summary

Benefits of technology

[0018]Application to the bag of the invented device is the only operation needed to obtain improved applicability of the fastening means and increased elegance for the bag, with or without the presence of handles. Recalling what has already been said about residual drawbacks attending known fastening means, it may be deduced that the presence of even only one decorative object makes it easier to handle the bare tape thereby lessening the risk of superimposing adhesive parts and also facilitating application at the correct point needed for securely joining the two edges of the bag.

Problems solved by technology

Unless care is taken, in fastening the bags with adhesive tape or labels, the glued sides may become superimposed and stuck together rendering the fastening useless.

Even so, the risk of superimposition of surfaces still remains as it is no easy matter to manage the bare tape holding it with the finger tips, especially if hindered by the string handles on such carrier bags.

These practical drawbacks are inherent in the use of adhesive tape for fastening purposes, quite apart from its aesthetic limitations.

Besides, due the central position of the bow between the two lengths of adhesive tape, it seems a device inadequate to fasten bags like gift shoppers with two edges to be joined.

The main drawback of the apparatus (and method ) of the last citation is that it doesn't allow to obtain fastening devices constituted by a length of only adhesive strip with attached at one end a decorative object selectable among a large variety of possible ones (e.g.: pompoms, stars, etc. and non-ribbon-type as cockades).
