• the paper is pulled by an operator. When the desired length has been pulled the operator pulls the paper down to expose a serrated knife 26 which then cuts off the paper.
• a lever 24 then springs back into the position shown leaving a length of spiral between the knife and the opening for the operator to pull and cut off when next the packaging is required.
• the paper can be supplied as a roll which, when replacement is required, can be slid in from the rear end of the container.
• the container can be supplied in a box 28, which as shown in Figure 2, can be dropped onto the base 30 with the front of the container abutting a wall 32 having the opening 20 and with the rear base of the container abutting a lip 34.
• the top of the wall 32 has a ledge 36 which prevents the front of the container from rising up.
• Side walls 38 prevent transverse movement of the container.
• the container may have an open front wall or an opening in the front wall to correspond with the opening 20.
• the front wall or opening in the container may be made by an operator detaching part of the container.
• the container may be made of cardboard.
• the front wall 32 may have a cone extending towards the cutter and tapering inwardly towards the cutter.
• the container will be fastened to a work bench.
• a shaft 40 extending down the base 30.
• the shaft 40 has a plate 42 slidably mounted thereon with the plate 42 including a pair of clamps 44 which can hold the device in place at the desired elevation above the work surface of the base by holding a work surface between the clamps 44 and an upper facing surface 46 of the plate.
• the device could be clamped to the rear of a work surface with the container projecting forwardly over and spaced from the work surface. Accordingly the space on the work surface beneath the container remains free to use.
• the container Whilst the container is shown with its elongate axis being horizontal, this angle can be altered.
• the base 30 is connected to the shaft 40 by a pivot bolt 48.
• a quick release and lock lever 50 is provided to allow angular adjustment such that the axis can extend at 10°, 20° or 30° or any desired angle to the horizontal.
• a further quick release lock lever 51 allows the container to be swivelled on the shaft 40.
• the outlet of the opening 20 is approximately one third of the outside diameter of a new roll.
• the outside diameter of a new roll may be 150 mm and the roll may have a length of 375 mm.
• the roll has a diameter of 220 mm with the opening 20 being 127 mm in diameter.
• the opening 20 may be 20, 30, 40, 50, 60 or 70 mm in diameter.
• a shelf 52 extends from the front of the container to the cutter 12 at a lower elevation than the cutter. Opposing sides 54 of the shelf extend upwardly and support the cutter at their free end.
• the guard 56 extends to a greater height than the knife 26 and to the front and rear of the knife along the complete length of the knife by an upwardly extending slot 58 of the guard substantially enclosing the knife.
• the lever 24 can be urged downwardly by the paper being pulled downwardly out of the device to expose the knife and cut the paper.
• the lever 24 is mounted on a pivot 60.
• the guard 56 is mounted on a pivot 62.
• the guard and lever are connected at both sides by an operating plate 64 which is itself mounted about a pivot 66.
• a pin or roller 68 fast with the plate extends through a slot 70 in the lever 24 and another pin or roller 72 fast with the plate 64 extends through an arcuate slot 74 in the guard 56.
• spiral can be pulled out of the container by a pair of driven members upstream of the knife, as shown in Figures 8 to 12.
• a motor 78 drives a lower shaft 80.
• the shaft 80 extends across the machine to drive an upper shaft 82 via meshing gears 84 connected to both shafts.
• the motor can be stopped and started by an operator.
• each shaft a pair of members 86 rotate to cause a spiral between them to be pulled out of the container and to drive the spiral from the members 86.
• the members 86 may have resilient outer surfaces which may trap a spiral between them and may be compressed at their adjacent region.
• the members may have uneven external surfaces, such as a cog, which may each pass within the area swept the other member during rotation in order to bunch up the spiral or help connect the spiral or help the spiral maintain the relationship between the layers in the spiral or any combination thereof.
• the axis of the roll is shown as being horizontal in another embodiment the axis could be vertical with packaging being drawn downwards and the device may be adjustable such that it can be moved to the axis being vertical, for instance from a previous position shown in which it is horizontal.
• the container or box 128 is fastened to a bench 200 as previously described in relation to Figures 1 to 12.
• the box 128 is mounted, with the winding axis of the roll vertical, on a bar 202.
• Paper is packed in the box as previously described and the outlet of the box is in the form of an inwardly and upwardly converging cone 204.
• the paper spiral 122 is fed vertically upwards from the box and around a free running roller 206 having a centrally located circumferentially extending rib 208.
• the paper leaves the roller 206 in a horizontal direction and passes between a lower driven roller 210 and an upper idler roller 212 before passing out of a housing 213.
• the rib 208 on the roller 206 serves to maintain the spiral in an expanded form. If the rib 208 were not present then there may be a tendency for the spiral to collapse flat around the roller thereby decreasing the volume and reducing the effectiveness of the packing. At the sides of the roller the packing may be guided to maintain the packaging in the central region. Alternatively or additionally, the packaging may not need guides or may be guided centrally by the rib on the roller.
• the driven roller 210 is powered by a motor 214 which drives a first small gear 216 and a second, spaced large gear 218 via a chain 220.
• the gear 218 is mounted on the same shaft as a large cog 222 which meshes with a small cog 224.
• the small cog 224 is mounted on the same shaft as the driven roller 210.
• powering the motor causes the chain to drive the gear 218 and the cog 222 which in turn causes the cog 224 and roller 210 to rotate.
• the feed rate of paper from the housing will be in the region of 76 m/min. If the cogs 222 and 224 are reversed from the position shown then the feed rate will increase to around 92 m/min for a constant rate of rotation of the gear 218. Thus the same motor at the same speed can be used to drive the paper at different speeds.
• the idler roller 212 is mounted at the free end of a swinging arm 226.
• the arm 226 is pivotally mounted on an opposed end and is biased by a spring 228 such that the roller 212 is biased towards the driven roller to trap the paper between the rollers 210 and 212.
• the housing 213 is pivotally mounted on the bar 202 and can move through approximately 30° to direct the feed from the horizontal position shown in Figure 13 at an angle down towards the work bench 200.
• the adjustment is effected by relaxing bolts 230 that hold the housing on an arcuate mount 234 at the top of the bar 202 and rotating the housing in a clockwise direction with the bolts moving through arcuate slots 232 in the mount 234 and then tightening the bolts 230 again when the desired angle is reached. That angle may have the bolts located at the ends of the slots or at a position between the ends.
• the paper is loaded into the machine, at the start of a new roll of packaging, by pivoting a cover 236 upwardly about a pivot 234.
• the paper is then fed around the ribbed roller and then passed to the driven and idler roller.
• Handles 238 on either side of the housing can then be rotated manually to manually rotate the driven roller and thus feed the paper through the rollers.
• Paper may be arranged to be fed at a length determined by an operator. For instance an operator may actuate a foot switch that causes paper feed with release of the foot causing the feed to stop. Alternatively or additionally, the feed may be in predetermined lengths (which predetermined lengths may be able to be altered) by an operator activating a switch.
• Detachment of the fed paper from the housing may be effected automatically, such as a blade (not shown) sweeping across the outlet of the housing.
• detachment may be effected by an operator actuating a switch or by the operator pulling the paper sideways relative to the outlet as described in relation to Figures 1 to 12.
• the drive may be arranged to automatically withdraw another length of the packaging such that the operator does not have to initiate a further withdrawal procedure after having used the previously detached length of packaging. In this way packaging time is reduced.
• the paper withdrawn from may be recycled paper.
• the spiral of paper which may be in tube form, may be used to fill voids in containers to cushion items in the containers. When the spiral is rolled into a coil the material may be able to support heavy objects, for instance up to 100 kg in weight.
