1,165,804. Packaging-machines. RHEEM INTERNATIONAL Inc. 26 Jan., 1967 [9 Feb., 1966], No. 3850/67. Heading B8C. In packaging products, such as turkeys 101, the products are fed into an elongated feeding shoot 90 through opening 94 and are successively moved longitudinally therealong and discharged therefrom to receive a wrapping of tubular packaging material 102 previously stored in shirred condition on the shoot 90, and then pass to a double clipping device 106 which closes the end of one package and also closes the end of the tube of packaging material ready for the next operation, there being severing means to sever the packaging material therebetween. An elongated length of labelling material may be fed inwardly of the packaging material and removed from the shoot 90 with the packaging material for incorporation in the packaged product. The clipper 106 is of known type which deforms a pair of U-shaped staples 107, 108 about the material 102 at adjacent but spaced-apart points therealong and incorporates a knife operated by an air cylinder to cut the material between the applied staples. The clipping device is provided with means around which the packaging material, in rope form, can be looped before it is clipped, so as to form a handle 121 on the packaged product, Figs. 3 and 5. In this instance the clip 108 has to engage through a double thickness of material and for this purpose has longer legs than the clip 107 whilst the punch operating thereon is shortened so that the final closing of the two staples takes place simultaneously to prevent unbalanced loading on the operating piston. |
