ABSTRACT:
There is provided a new arrangement for pressure sensitive labels mounted along a carrier strip, and also a new method and means for removing these labels from the carrier strip and applying them to a product. The label carrier strip is divided down its middle forming separable halves, with the labels mounted over both halves. The separable halves carrier strip is pulled along a plate towards a V-shaped notch in one edge of said plate. The V is somewhat wider than the carrier strip. At the notch, the two halves of the carrier strip bend and are drawn through the V-shaped notch, each half over a different side of the V. This causes the two carrier strip halves to follow divergent paths from each other, and also from the label, forcibly releasing the label from the carrier strip halves. The label is thereby forced to continue in a straight line over and past the V-shaped notch until it is free of the carrier strip. It cannot follow the carrier strip halves through the V. The label is accompanied, during this process of removal by a vacuum equipped application device, which is attached to the label before, while and after the label passes over the V-shaped removal zone. The application device then carries the label a safe distance beyond the V-shaped notch and applies it to a product. The application device can be a bellows with holes in its face for vacuum, and extendable by air pressure. In manufacture, labels are formed by positioning a web on a carrier strip, die cutting the web to form labels and then removing the web waste, leaving the labels mounted on the carrier strip. With this invention, the label-carrying web need not have had its waste (matrix) removed from between and around the labels during manufacture.
