Abstract: A method and apparatus for reestablishing the spinning operation at a spinning station of an open end spinning machine after a yarn break or after completion of winding of a full package. A traveling piecing unit responds to signals at a spinning station that indicate that a yarn break has occurred, that a package changing operation has occurred, or that winding of a package has been completed. Independently, a traveling package changing unit responds to a signal indicating that winding of a package has been completed at a spinning station and performs the package changing operation. When the piecing unit responds to a yarn break at a spinning station, it locates and withdraws the end of broken yarn from the package and positions it in a position where the unit then feeds the end to the spinning element to piece it with new yarn being spun and then releases it to the package, which resumes winding.

Abstract: Side registration is provided for a web during its forward movement by lateral movement of the web causing one side edge of the web to engage a registration edge guide, by moving the web sideways with self-skewed pivotal rollers engaging and driving the web at their nip. Two separate roller drive systems with a slight speed differential are utilized in cooperation acting on the same web. A downstream, fixed nip, non-slip, roller drive system drives the sheet in its primary direction of movement, at a first driving velocity. Simultaneously, the same web is driven at an upstream position by a pivotal nip drive roller system. This upstream (pivotal nip) roller system is mounted on a pivot arm to pivot therewith, and is driven at a second driving velocity which is slightly lower than the first driving velocity of the other, downstream, roller drive system.

Abstract: A spinning machine has an electric motor for rotating a bobbin-supporting spindle to build a package of yarn thereon and a funnel for guiding yarn onto the spindle. The spindle is rotatingly driven by an electric motor and the electric motors of the spindle and the funnel are commonly connected to a frequency control means which is, in turn, connected to an electrical power supply means. The torque of the funnel electric motor is a function of a characteristic of the funnel in accordance with the relationship that the funnel is rotated by its electric motor at a lower rate relative to the contemporaneous rate of rotation of the spindle. The apparatus can include a switch assembly selectively movable between leads for selectively connecting the funnel electric motor to the frequency control apparatus to operate the motor or to the electrical power supply means to brake the motor.

Abstract: This is a sole with compressible shock absorbers which not only provides an improved shock absorbing function but also provides more comfort for the wearer. The shock absorbers consist of a polygonal replaceable air bellows placed in a polygonal recess on the forefoot section of the shoe and a cylindrical replaceable air cylinder placed in a circular recess on the heel section of the shoe. The air cylinder and air bellows are made of an integrally resilient air-tight material such that, during exercise, the shock absorbers absorb and then return the energy in a controlled upward direction, by way of the bellows-type body and the friction caused between the inside wall of the recess and the bellows itself. Moreover, since the shock absorbers can be placed easily by hand, the wearer can adjust the shoes in line with his weight and type of sport performed.

Abstract: Contactless support guides serve to create a cushion of pressurized air to hold a web of material such as paper spaced from a support face. The support face can be curved to transport the web through an angular deviation. The support face contains a large number of shallow pockets at least some of which emit air to create the cushion. Special additional pockets or slats are provided to create zones of higher pressure in the regions of the cushion where the web enters and exits the guide.
