  • Patent number: 7793532
    Abstract: A protective sheet loader may comprise a first roller, a second roller, a sheet of material spanning between the first and second rollers, and a loading mechanism. A portion of the sheet of material may be loaded into the crimping chamber of an apparatus for reducing the size of a medical device. A medical device may be placed within the crimping chamber such that the sheet of material forms a barrier between the walls of the crimping chamber and the medical device and prevents cross-contamination between the medical device and the crimping device. After a crimping step is completed, the medical device and the contaminated portion of the sheet of material may be removed from the crimping chamber, and a clean portion of the sheet of material may be loaded into the crimping chamber.

  • Patent number: 7596861
    Abstract: A vehicular body panel or component part having a reinforcing backing plate reconciled or joined to a part of a blank material at a position wherein a bending formation is implemented. The backing plate has one or more apertures formed in at least one lateral row at a location equivalent to the position of the bending formation. When forming the blank material and the backing plate concurrently by a bending operation, the backing plate becomes intimately associated with the blank sheet to avoid the backing plate from locally separating from the blank material and from forming a gap relative thereto, with a resultant improved product quality.

The plastic working system includes: a loop correction sensor 13 for watching a slack of a coil material C intermittently delivered from a preceding first press device 2a; and a second slack watching means 19 for watching a slack of the coil material C generated at the time of sending the coil material C to a succeeding second press device 2b. According to the slack generated by intermittent feeding of the coil material C sent from the first press device 2a, intermittent feeding is converted to continuous feeding by the feeding means 15. At the same time, the continuous feeding speed is subjected to speed increasing/decreasing control. On the other hand, by the second slack watching means 19, a slack of the coil material C is watched at the time of feeding the coil material C to the second press device 2b and the preceding first press device 2a is subjected to speed increasing/decreasing control.
