Abstract: A core for winding sheet material is proved. The core comprises a cylindrical tube having a longitudinally oriented slot formed therein, and a strip of soft material located in the slot. Because of the geometry of the slot and the strip, the strip may be softer (less compressed) in the central region but firmer where the core transitions from the relatively soft strip to the relatively hard tube. The leading edge of the sheet material imbeds itself into the soft central region of the strip as additional layers are wound around the core.

Abstract: A control mechanism for loading/unloading data storage tape is provided. The control mechanism is part of a tape drive that receives a removable tape cartridge. The tape cartridge stores the data storage tape that is movable using the control mechanism. The control mechanism includes a plurality of gears, together with a cam. A leader assembly is operably connected to the control mechanism. At least portions of the leader assembly are movable in connection with loading or unloading the data storage tape relative to the leader assembly.

Abstract: The present tape cartridge leader includes a flex relief aperture, located in the body of the tape cartridge leader between the guide wings. This flex relief aperture enables the tape cartridge leader to bend in a tight radius as the tape cartridge leader is pulled around the tape guide rollers in the tape drive, thereby ensuring that the tape cartridge leader is properly seated on the tape guide rollers as it traverses the tape path in the tape drive. The flex relief aperture also reduces the possibility of cracks forming in the tape cartridge leader where the guide wings meet the body of the tape cartridge leader, which is a problem in existing tape cartridge leaders. The guide wings are also shaped with a lead in radius to reduce to possibility of damage to the guide wings. In addition, the trailing edge of the guide wings includes a lead in chamfer to aid in the guide wings engaging the guide track in the cartridge housing.

Abstract: A leader pin assembly for attachment to tape as a generic and space-efficient interface between tape and equipment which manipulates the tape, and a method for making the same. The leader pin assembly preferably includes a leader pin, an elastomer element, and a clip. The leader pin is barbell-shaped, having enlarged ends and at least one pair of flanges each spaced a distance from a respective enlarged end to define a pair of recesses and a center section of the leader pin. The center section of the leader pin is sized to permit tape to be wound around the center section, with the elastomer element surrounding the tape and with the clip snugly surrounding the elastomer element to keep the tape securely in place around the center section of the leader pin. The end surfaces of the leader pin may have an outward curve to ensure smooth movement across equipment surfaces during leader pin assembly manipulation. Also the edges of the leader pin may be radiused.

Abstract: This invention aims to provide a package of a terminal series strip which can make full use of the last terminal metal fixture 11 on a leading end of a terminal series strip 10 wound around a bobbin 14 as a package. The leading end of the terminal series strip 10 is connected through an auxiliary strap 17 to the bobbin 14. Even if the leading end is paid out from the bobbin 14 after the terminal series strip 10 has been almost paid out from the bobbin 14, the auxiliary strap 17 is maintained to be connected to the bobbin 14. Thus, the terminal series strip 10 can be maintained to be hung between the bobbin 14 and a crimping apparatus until the last terminal metal fixture 11 on the terminal series strip 10 is press-worked.

Abstract: A method and device for the production of cover strips which are to be inserted into the grooves of stators of electric machines, from a supply of strip material provided on delivery rolls. The guide channel (26) for cover strip material (12) has several feed passages (46, 46'), which can be brought individually into connection one after the other with the main part of guide channel (26). Thus it is possible to thread the lead of a new delivery roll into its feed passage (46, 46') of the guide channel while the machine continues to run, so that when delivery rolls (16, 16') are to be changed, only a mechanical change of position of feed passages (46, 46') need be undertaken. The down time of the machine is thus greatly shortened.

The supply roll when rotated by the reel positions the leading edge of the supply roll with its adhesive strip against film web dispensed from the expiring roll, so that the leading edge of the film web of the supply roll is carried off the roll, with the sleeve member being carried off of the guide member.

Abstract: A continuous web converting machine is supplied with web material from a spider wheel unwind stand having a shiftable wheel axis. Movement of the spider wheel axis is regulated by a double acting fluid cylinder for controlled force application of the working web supply reel against a closed circuit pulling belt. Depletion of the working reel is detected by a limit switch actuated by contact with the shift carriage. upon working reel depletion, the pressure bias on the fluid cylinder is reversed and the shift carriage retracted to free the working reel from contact with the pulling belt. Thereafter, the spider wheel is rotatively indexed 120.degree. to align a full reel in the working position. Said full reel is prepared with a strip of double faced adhesive tape secured across the full reel web leading edge to facilitate web continuity and splice from a depleted reel to a full one.
