Abstract
Abstract A clipping apparatus for forming a closure around the neck of a bag of flexible material or the like. Clips are supplied to the apparatus in the form of an elongated prestamped strip of planar sheet material which is wound on a supply reel. The strip is then formed to a generally U-shape in the device and thereafter individual clips are cut from the strip by a punch which, in cooperation with a die, applies the clip in encircling relationship to the product. The disclosed prestamped strip facilitates feeding of the same to the clipping operation and the shape of the clip facilitates use of the machine with clips having legs of different lengths.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
Means for forming a closure encircling a product such as a plastic bag or the like comprising: an elongated strip of sheet material having a central body portion extending along the central axis of said strip, a plurality of longitudinally spaced apart legs extending laterally outwardly from the opposite sides of said body portion and at right angles to said axis with the side edges of said legs being substantially perpendicular to said axis, the legs on one side of said body portion being in staggered relation relative to the corresponding legs on the opposite side of said body portion, whereby a pair of adjacent legs on opposite sides of said body portion may be bent in parallel planes perpendicular to said axis to form a closure around such product.
Claim 2
Dependent Claim
130 words
