A crimper assembly for sealing overlapping layers of a packaging material comprises, an upper and lower crimper 32, 34 having a surface formed from one of either a rigid material or a resilient material, the crimping surfaces of said upper and lower crimpers being movable so as to engage and compress the overlapping layers of the packaging material therebetween. The crimper assembly may include upper and lower rotating crimper bars to which the upper and lower crimpers 32, 34 are mounted, so that during operation, the crimpers 32, 34 are rotated such that the overlapping layers of packaging material are compressed between the downwardly and upwardly facing undulating surfaces 43,54 and sealed together to form a trailing edge seal for a packaged article. A cutting blade 45 may be mounted in the upper crimper 32 and cooperate with an anvil 47 mounted in the lower crimper 34 to cut the sealed packaging material into individual units. |
