A crimper assembly (32) forms end seals in overlapping portions of the sheet of packaging material after being folded about an article. The crimper assembly includes a crimper including a base (42), an insert (46a,47a) that is formed from a resilient material, and a support plate (48,49) that is formed from a rigid material. The insert (46a,47a) has a surface that is adapted to engage and seal overlapping layers of a packaging material. The insert (46a,47a) is disposed between the base (42) and the support plate (48,49). The support plate is secured to the body to retain and support the insert thereon. The insert and the support plate may be formed as separate pieces or may be secured together as a single piece. To prevent excessive compression of the insert, the insert can have an aperture (46c,47c) formed therethrough, and the support plate can have a protrusion (48c,49c) formed thereon that extends through the aperture into abutment with the base. Alternatively, the insert can include a pair of bushings, and such bushings are engaged between the base and the support plate to prevent excessive compression. |
