  • Patent number: 4997513
    Abstract: Preimpregnated fiber reinforced tapes, so-called prepregs, are dispensed and deposited in a molding and bonding apparatus by a device in which a supply spool or roller carrying the tape is supported by a carrier having an adapter for connection to an arm of a conventional industrial robot. The carrier also supports feed rollers for advancing the tape and a cutter for cutting the tape. The feed rollers are secured to a support which in turn is secured to a fixed member by guide elements and biasing springs for a vertical guiding of the support movement. All drive members are controllable, so that all functions can be performed under the control of a computer in accordance with a program stored in the computer. Thus, the tape dispensing, application, and cutting takes place substantially automatically.

  • Patent number: 4548345
    Abstract: This automatic riveting machine can access confined component parts, has a imple sensor system to locate component part edges which allows it to be used in special equipment or in robots. The riveting machine has a mounting bracket to which a rivet supply unit, a riveting unit, and a drill feed advance unit are movably attached. A pneumatic cylinder drives each unit from its resting position into the operating position while shock absorbers brake these movements. Another pneumatic cylinder locks all units into the resting position when the compressed air supply in interrupted. The rivet supply unit pneumatically shoots single rivets into pre-drilled holes in the component parts. The riveting unit is constructed as a so-called alligator riveting press which clamps the component parts together and presses or rivets the heads of the rivets. The drill feed advance unit drills holes into multiple component parts while locating their edges, pressing them together, and compensating for any positional tolerances.

  • Patent number: 4525918
    Abstract: A tool, such as a drill bit, cutting tool or any other suitable tool, is d in a two component tool holder. The first component (1) includes a holder sleeve (3) with a conical bore (2). The sleeve (3) is held in a housing (19) carried by a machine tool, robot or the like. The second component (25) which carries the tool proper has a conical shaft (26) with a locking groove (29) near its free end. The conical shaft (26) locks into the conical bore (2) in the sleeve (3). An additional automatic locking is provided by at least two locking bolts (12) located to reach radially through the sleeve (3) into the locking groove (29) when the shaft (26) is inserted into the conical bore (2) of the sleeve (3). The locking bolts (12) are biased by springs (14) into the locking position and pulled out of the locking position by pneumatic or hydraulic pressure operated elements.

  • Patent number: 4244669
    Abstract: A cutter head for cutting templates from cardboards, plastics, and the like, which includes a high speed rotatable cutting stylus, and a holding-down device for holding down the material from which the templates are to be cut out. The holding-down device surrounds the cutting stylus and is firmly but adjustably connected to a non-rotatable but axially freely movable member of the cutter head.

  • Patent number: 4173020
    Abstract: An automatic drafting instrument of the type supporting a plurality of stylographic pens above a drafting surface. The instrument includes a reciprocating mechanism for lowering the pens from an upper rest position to a lower drafting position in contact with the drafting surface. The device is characterized by a vertically actuable and pivotable sealing element which engages the writing pen tip in its rest position and is actuable vertically downwardly and pivotably away from the pen as it is lowered to the writing surface.
