DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates generally to a label applying apparatus, and more particularly to a label applying apparatus of the type capable of printing adhered sides of labels or objects with a lot number, an effective date and a production data and further, interposing a layer to be printed between the label and the object.
Background Art
A dry printer (hot stamp) has been heretofore used to apply a lot number, production date, etc, to articles. This machine is arranged to transfer gold leaf to the articles by heat and thus incorporates inherent deficiencies in that the printing speed is reduced to less than half as compared with a situation where the articles are printed in ink and further, the characters, letters, etc., do not reproduce well due to lack of moisture. In the prior art printing, the labels or the object itself are printed so that indicia such as a lot number and/or production date thereon may be delible. They are thus susceptible to alteration. However, especially for pharmaceuticals, manufacturers are required to print such indications so as to render them indelible or unalterable.
Therefore, an improved labelling process and apparatus has long been desired.
It is, therefore, the primary object of the present invention to provide a label applying method and apparatus by which the articles are printed with better results without decreasing the applying speed and which prevents indicia on labels from being altered.
Another object of the invention is to provide a label applying apparatus which affords higher reliability of label separation from a strip and application of the labels to the articles.
Disclosure of Invention
According to the present invention, a plurality of labels which temporarily and independently adhere to a strip on an elongated carrier means are successively peeled from the strip.
In this separation, the labels are charged with static electricity. This static electricity contributes to the turning over and separation of the labels when fed to the next station such as the label applying means with adhered surfaces thereof directed outwardly. Further, in accordance with the present invention, the labels are applied to the objects to be labelled or the articles in such a manner that a layer to be printed may be interposed between the adhered surfaces of the labels and the articles so that printed characters, letters and patterns or the like on the labels are distinctly maintained to make alteration of such indications impossible.

BEST MODE FOR CARRYING OUT THE INVENTION
The above and other objects of the present invention will become apparent from a reading the following description, taken in conjunction with the accompanying drawings, wherein like numerals are used to designate like parts.
Numeral 1 designates a supply roll for supplying labels 5 which are adapted to be peeled off from a strip 3 such as a plastic sheet of polyester and the like in a path from the supply roll 1 to a take-up roll 6 for winding the strip thereon.
Numeral 9 is a rotary shaft for the take-up roll 6 to which rotation is imparted by a drive shaft 21 as will be described hereinafter via a rubber belt 9B (FIG. 3). It is noted that during operation of brake rolls 7A, 7B elongated carrier mean
