A positionally based label application system includes a plurality of sensors which detect the pitch between the products to be labeled as well as the location of those products. A supply web bearing labels is caused to pass over a peel tip which feeds the labels into a nip point. This allows the labels to be precisely matched with products traveling at a very high rate of speed.The positional system determines a desired ratio of movement between the supply web and the product being conveyed, this ratio being based upon the detected pitch. In this manner, the supply web is allowed to move continuously, but at a slower speed than the products being conveyed, but still precisely matches labels to products.
