Abstract: The present invention provides a cold rolled steel sheet and a hot dip zinc-coated cold rolled steel sheet excellent in paint bake hardenability, non-aging properties and formability, and a process for producing the same. In the present invention, an extremely low carbon steel or extremely low carbon steel containing at least one element selected from the group consisting of Ti and Nb is used as a base steel, and Mn and Cr are positively added thereto, whereby the resultant steel has a mixed structure after annealing. Accordingly, there can be obtained a steel sheet having both a high paint bake hardenability and non-aging properties, and being excellent in formability such as an average r-value (deep drawability). With regard to the paint bake hardenability, the present invention may provide a cold rolled steel sheet and a hot dip zinc-coated cold rolled steel sheet to which paint bake hardening may be optionally imparted in an amount as large as about 10 kgf/mm.sup.

Abstract: An apparatus for automatically supplying cops to a winder includes a cop-feeder which moves along a track of the winder, the cop-feeder including means for stopping same in registry with each winding unit of the winder, storage for cops, a cop-feed-out section, a charging section for transferring cops from the feed-out section to the magazines of the winder, and means for grasping a yarn end and transferring same to a fresh cop. The apparatus also can determine whether a magazine has its full supply of cops, selectively halting the cop-feeder only at magazines which have an incomplete complement of cops and supplying the needed number of cops to the magazines. The travelling mechanism permits the feeder to stop only at every other magazine during a run in one direction along the track and at the remaining magazines on the return trip. Provision is made for feeding cops to magazines while the magazines are in rotation.

Abstract: This invention relates to a method and an apparatus for automatically supplying cops to a thread winder wherein the inefficient manual operation of supplying the cops one by one into each of the cop-holding magazines mounted in juxtaposition to the thread winder can be dispensed with. To this end, the apparatus of the invention comprises, as an essential component, a travelling cop feeder with means for sequentially feeding a number of cops from a cop-containing section through a cop feed-out section thereof, means for receiving and holding the cops by a cop-holding and charging section mounted in the cop-receiving position below said feed-out section and transferring them automatically alongside the thread winder, means for stopping said charging section in a position registering with each cop-holding magazine in the thread winder by a stop position control device, and means for charging the cops into the cop pocket in said magazine.
