The invention relates to nailing apparatus for use in making cable reel flanges or the like. Apparatus according to the invention comprises a rotatable element housed in a work support table of the apparatus and movable to cause a work-engaging surface of the element to raise a workpiece from a support surface of the work support table into a position in which the work-engaging surface supports the workpiece and provides a turning center so that the workpiece can be easily turned relative to nai...

An electrostatic copying machine having (1) a xerographic surface on which a latent electrostatic image is formed, (2) a developing station for developing the latent image by contacting the latter with developer material, and (3) a transfer station for transferring the developed image to support material, has a developer material replenishment device which replenishes developer material in the developing station in accordance with the amount of support material fed to the transfer station.

A device for inserting coupons in cigarette packets, in particular in hinge lid packets, includes a guide rail 14, 16 parallel to the packing conveyor 2 for raising the lower edge 11 of the inner frame 10 away from the cigarette bundle 6 so that a coupon C can be fed edgewise under the gap. A plough rail 48 may push down the inner frame on to the coupon after it has been inserted.

The copier machine of the present invention comprises a second charger having a grid and is capable of executing a mode wherein a toner is deposited onto the latent image exclusive of the outline portion thereof to visualize. When this mode is designated, the grid is applied with the voltage which is lower than the surface potential at the image portion of the latent image and higher than the surface potential at the non-image portion of the latent image.

An embroidery and applique machine having a number of article feeding modules, each adapted to supply articles such as sequins which are to be appliqued in alignment with a needle. The feeder modules are mounted on a carriage for movement therewith. A motor moves the carriage back and forth along a fixed path relative to the needles. An indexing mechanism is effective for stopping the carriage at any one of a number of positions in which the feeder modules are in register with the needles for su...

A braiding machine of the maypole form having co-acting horngear assemblies positioned in a cylindrical housing and arranged to drive spool carriers along a double undulating and intersecting drive track groove as groups in opposed directions. The form of the groove is such as to avoid discontinuities both in normal and in tangential components of acceleration forces on the spool carriers. Drive is transmitted from the horngear assemblies to the spool carriers by drive forks each carried on a pi...

There is disclosed a rotor for an electrical machine, the rotor having a current-carrying winding comprising a plurality of circumferentially distributed winding portions which lie in at least one plane perpendicular to the rotor axis, and extend from a radially inner region to a radially outer region. A commutator is provided by surfaces of the winding portions at the inner region, and the winding is formed from a plurality of conductive sections, each having ends which lie at said outer region...

A module for textile machines has a plurality of tools (2) with retention portions (6). The retention portions are grasped in a plastic body (7), which reaches out or embraces the retention portions (6) at one or more recesses (15, 27, 28). The plastic body serves to fix the tools (2) positionally correctly with respect to one another. The positioning of the tools (2) with respective to a dividing sinker (11), however, is effected by direct contact between the retention portions (6) and the divi...

A guard device for machines such as bending presses, cutting machines, stamping machines or the like, has a first machine part which performs operative movements toward a second machine part. A laser photoelectric detector arrangement is attached to the first machine part and possesses at least one photoelectric detector, whose light beam shines in an adjustable secure distance from this machine part. On interruption of the light beam the operative motion is arrested. An abutment arrangement on ...

A method of assembling an electric machine generally includes heating a housing to thermally expand the housing. The housing is allowed to cool and thermally contract against an end shield and a rotor assembly such that interference fits are formed between the housing and the end shield and between the housing and the rotor assembly.
