  • Patent number: 5353576
    Abstract: Copies (22) of preferably folded or stitched printed matter are transferred by means of a loading device (20) from a preceding station to a stacking device (30). The copies (22) are stacked in the stacking means (30) into stacks (120), positioned on a bottom (96). The bottom (96) can be lowered together with the stack (120) lying thereon. During this movement, the bottom is lowered simultaneously into a banding means (106) which applies itself to the bottom and the side walls of the stack. Thereafter the banding means (106) is closed tightly on top of the lowered stack (120), by means of sealing rams (118). The stack (120), with the loop wrapped around it, is then carried off, and the lowered bottom (96) or its partial bottoms (98, 100) return to their upper position.

  • Patent number: 4953344
    Abstract: For applying a covering to glass fibre insulation batts, the batts are deposited in succession into a vertically elongate batt stacking space to form a stack of the batts, and upper and lower compression plates each having a concave compression surface the shape of which compression surfaces correspond at least substantially to the shapes of convex upper and lower surfaces of the package, are displaced vertically by an amount sufficient to compress the stack between the upper and lower compression surfaces with a compression ratio of 6:1 to 11:1. A covering of flexible sheet material is then provided around the compressed stack to maintain the stack in a compressed state. The concave compression surfaces make possible a higher compression of the batts than was possible with the flat compression plates used in the prior art, without damaging the batts and therefore while allowing satisfactory recovery of the batts when released from their compressed state.

  • Patent number: 4858416
    Abstract: A packaging machine is provided for packaging bundles, optionally under compression, with tensionless cross-seals. One problem of conventional devices is that movable sealing bars tend to rupture film as it is pulled together around materials to be packaged, particularly if the materials are relatively high or heavy. Packaging products under compression is an additional challenge. In this instance, packages are generally fed substantially at a predetermined speed between upper and lower webs of film, which are then sealed at their sides. Compression of the products being packaged may be optionally practiced during such side seal formation, and later during cross seal formation. Subsequently, the products enclosed in the side-sealed web of films move into a cross seal area, optionally including a reciprocatable carriage, operation of which in effect causes the product being sealed to move backwards relative to seal bars forming a cross seal therefor.
