Abstract: A rotating perforation apparatus contains a plurality of needle points (or other piercing features) formed along a free-wheeling support bar, where the bar is positioned to contact the film while it is being unrolled and is in a ‘tensioned’ state (in some embodiments, immediately prior to contacting the element to be wrapped). In particular, the free-wheeling perforation apparatus contacts a mechanized film roller such that the exposed needle points will rotate against the mechanized roller and make the perforations in the film as it travels over the film roller. As long as the film roller is formed of a pliable material, the needles will pierce the film and create the desired perforations. The size and placement of needles can be adjusted to provide the required pattern of perforations, as well as dictate the size of the actual perforations.

Abstract: An overwrap packed body is obtained by heating and shrinking a wrapping material in a condition that five drink products collectively wrapped by the wrapping material. Three perforated lines passing through gap portions between the adjacent drink products are formed on the wrapping material at an interval of 2 mm in parallel. When the three perforated line portions are pushed with fingers in the gap portion between the adjacent drink products, the wrapping material torn from the pushed portion in a vertical direction. Thus, the packed drink products DG can be easily taken out one by one.

Abstract: Apparatus for cutting an advancing strip of photographic paper into prints of different size along and across the strip. The apparatus includes devices that cut perpendicular to the edges of the strip upstream of devices that cut parallel with the edges of the strip. Other devices secure the paper in position while it is being cut.

Abstract: A system is provided which utilizes a plurality of sequentially controlled magnetic repulsion punches arranged in a variable array to punch a constantly moving substrate. These punches are disposed adjacent the constant velocity substrate on which holes, or vias are formed as the punches are sequentially fired. The array of punches is placed at an angle with respect to the perpendicular of the direction of movement of the substrate. Thus, a delay is present between the time when the first punch must be fired and the firing of subsequent punches, due to the angle of the array. Therefore, due to this delay between the time the first punch must energized, and the energizing of subsequent punches a single power supply is capable of providing energy to a group of punches.

Abstract: The music roll perforating system permits a paper music roll to be perforated from a special previously prepared magnetic tape containing a digital recording of a music rendition. The process and apparatus disclosed uses a small computer to drive a music roll perforator through a driver box. The driver box accepts a serial data stream from the computer and converts it into parallel channels with high current/high voltage outputs capable of driving the solenoids used in a conventional music roll perforating machine.A magnetic tape recorder is attached to the computer for the dual purpose of either loading a computer program into the computer following turn-on or for reading the specially prepared digital recording into a computer memory. A Teletype machine is also attached to the computer to permit input to the computer from an operator.

Abstract: A system for limiting maximum material speed for predetermined board length in a corrugator cut-off machine provides an output pulse for each increment of material movement. A divide circuit is connected to the pulse generating means and there are a plurality of gates, with each gate being placed in a predetermined condition for a predetermined range of board length. A counting circuit is connected to the gates and to the pulse generating means. The counting circuit compares material movement with a predetermined maximum speed for each range of board length and when material speed is greater than the predetermined speed, an output signal is provided which may be used to reduce the speed to a predetermined safe speed or to sound an alarm.
