DESCRIPTION:
BRIEF SUMMARY
The subject-matter of the invention is an apparatus for applying decorative elements which are covered with a hot adhesive on one side to a flat article lying on a table, comprising a heating element for heating the hot adhesive and a means for pressing the decorative element onto the flat article.
Articles of clothing for festive occasions and the robes of circus performers or variety artistes frequently bear decorative elements, which are referred to as stones, consisting of ground glass or material similar to mother of pearl. Depending on the particular use involved, a few up to some hundreds of stone are stuck on to an article of clothing. The decorative elements which are generally of a part-spherical shape are applied to the flat contact surface with a hot adhesive which softens under the effect of heat and which provides an insoluble connection to the article to which it is applied, being in most cases a flat textile article.
It is known for the decorative elements to be individually applied by hand to the material which is to be decorated and which lies on a heating plate, and for the decorative elements to be pressed thereagainst either individually with a rod or overall with a plate.
That work is very costly and irksome, particularly when the individual decorative elements are only about 1 millimetre in diameter and consequently can scarcely be held by hand.
It is also known for the decorative elements firstly to be applied to an adhesive carrier foil, in that case the decorative elements forming a pattern. The decorative elements which adhere to the carrier foil can then be jointly transferred on to the material to be decorated, using an iron.
That process is suitable only for applying a large number of decorative elements forming an ornament. The costs involved for applying individual decorative elements are excessively high and in addition, when dealing with materials of synthetic fibres, there is the danger that the material may shrink or form undulations as a result of the heat which is given off by the heating plate or by the iron.
The object of the present invention is that of overcoming those disadvantages and providing an apparatus with which the decorative elements can be applied inexpensively, quickly and accurately to a predetermined location.
The invention attains those objects generally by an apparatus of the type previously mentioned having the combination of the following features: a gripper with a punch member, the gripper being arranged above the table on a horizontal axis and being pivotable by means of a drive member into an upper and a lower limit position, a shaker device for isolating the individual decorative elements, and a rotatable disc which is arranged between the tip of the punch member in the upper limit position of the gripper and the shaker device and which engages into the shaker device and which has a bore terminating at its periphery and communicating with a suction source for sucking thereagainst and holding thereat a decorative element which is isolated in the shaker device, whereby a decorative element can be guided from the shaker device to the tip of the punch member by a rotary movement of the disc and from there can be guided onto a flat article by pivotal movement of the gripper into the lower limit position. In accordance with the invention, a heating element with a heating plate is arranged under the gripper in an opening in the table. The surface of the heating plate may lie below the surface of the table, and a light source may be arranged either in the opening or on a cantilever arm carrying the gripper.
It is now possible for decorative elements to be automatically taken individually from a storage means and applied to the material at a desired location. In that operation, the material is heated only precisely at the location of contact with the decorative element. It is therefore also possible to decorate voluminous materials such as velvet with decorative elements without visible pressure areas occurring outside the decorative elements.
