摘要： An improvement is provided for a conveyer tape comprising an underlying flexible belt, a stock of parts disposed in a row along such belt, adhesive deposited on the belt in two bands flanking such row, and a cover tape extending in the length of the row over the parts to hold them on the belt, the tape being adhered on laterally opposite sides of the row to the belt by adhesive in such bands. The improvement involves providing two sets of perforations formed in the tape to demarcate therein two tear lines extending in the length of the tape and disposed on opposite lateral sides of the row of parts, laterally inwards of the adhesive bands. The perforations reduce the shearing strength of the tape along the tear lines to promote peeling at the front end of the tape away from the belt of a central strip of the tape lying between the tear lines and between border portions of the tape on either side of that strip and remaining adhered to the belt. The removal of the strip exposes parts at the front end of the belt to access to permit such exposed parts to be lifted away from the belt.
