  • Publication number: 20090047109
    Abstract: A transfer wheel device for a slicer has a rolling pipe and an inner pipe. The rolling pipe is rotatably connected to the slicer and has multiple inlet holes formed trough an external surface of the rolling pipe. The inner pipe is rotatably mounted in the rolling pipe and securely on the slicer and has a linear suction array. The linear suction array is formed linearly on an external surface of the inner pipe and has multiple suction units. Each suction unit has a suction hole formed through the inner pipe to increase ease and effectiveness of the transfer wheel device.

  • Patent number: 5853529
    Abstract: A machine for cutting and fusing plastic plates includes a feeding means for feeding the plastic plates toward a first compressing device having a first supporting plate being flush with the feeding means, a first compressing plate controlled by two first cylinders disposed beside the first supporting plate, a cutting device disposed above the first compressing means and having a disk blade driven by a motor, the disk blade is moved with a belt movably reeved around pulleys disposed to a frame so as to cut the plastic plate fed by the feeding means. A second compressing means is movably connected to the first supporting plate and has a second supporting plate being flush with the first supporting plate and a second compressing plate which is connected to two second cylinders disposed beside the second supporting plate.

  • Patent number: 5843275
    Abstract: A machine for processing raw material plates includes a feeding assembly, a first transportation assembly for moving raw material plates to a front clamping assembly which is used to clamp a first raw material plate for subsequent cutting of an irregular front end of the first raw material plate by a front electric heating assembly. The machine further includes a movable table device for moving the first raw material plate to a rear clamping assembly for subsequent cutting of an irregular rear end of the first raw material plate by a rear electric heating assembly. The rear electric heating assembly has a further function for fusing the cut front end of the first raw material plate to a previously fused material web before the cutting of the rear end of the fused material web. A second transportation assembly is provided to feed the first raw material plate to the rear electric heating assembly.
