A yarn creel assembly includes a vertical frame, a plurality of vertically spaced package holders, and a vertically disposed arcuate yarn guide. The package holders are mounted on the frame and adapted for carrying respective yarn packages, whereby a tail end of a first yarn package is attached to a head end of a second yarn package. The arcuate yarn guide extends between adjacent package holders, and is adapted for guiding a moving end of yarn drawn from an emptying first yarn package and transitioning to a full second yarn package.

A bobbin holder adapter facilitates replacing bobbins in a yarn feeding system called a creel, and which is formed by bearing of a constant lower table and a movable upper table on a central shaft. Further, a motion restriction component is positioned on the upper table for restricting the motion of the upper table around the central shaft bearing the upper table and for stopping the adapter at the desired point, a motion restriction housing is formed on the lower table for enabling movement of the motion restriction component, a locking ball is provided for keeping the adapter in the optimum position for unreeling yarn, a locking spring is positioned on the upper table for applying force on the locking ball, and a locking housing is formed on the lower table, on which the locking ball makes pressure as a result of the force applied by the locking spring.

A pipeline-type positive warp yarn feeding device includes a yarn bobbin frame and a yarn feeding frame. The yarn feeding frame is provided with a positive yarn feeding assembly including a positive yarn feeding power component and positive yarn feeding wheels on the yarn feeding frame, the positive yarn feeding wheels correspond to yarn bobbins on the yarn bobbin frame, an outer circumference surface of a wheel shaft of each positive yarn feeding wheel defines spiral yarn feeding grooves, a groove mouth width of each yarn feeding groove is matched with a width of a strand of yarn, the yarn on the yarn bobbins is wound on the positive yarn feeding wheels, each yarn feeding groove accommodates a single strand of the yarn, and the positive yarn feeding power component is configured to drive the positive yarn feeding wheels to rotate and feed the yarn through a transmission gear assembly.

A system can comprise a plurality of containers that are coupled together as a movable unit. A plurality of container-feeding assemblies can be configured to simultaneously deliver respective yarns into respective containers of the plurality of containers. A header can be selectively attachable to a tufting machine, the header having a longitudinal axis. A retainer can be configured to extend across the header along the longitudinal axis to secure the respective yarns in respective positions relative to each other along the longitudinal axis.

A coil skid on which a hot-rolled coil 1 obtained by coiling a hot-rolled steel sheet is placed includes: at least two or more layers of a metal plate 11 and at least two or more layers of a heat insulating material 12 each stacked alternately, in which the metal plate 11 is in contact with the hot-rolled coil 1. The uneven cooling of an outer peripheral portion of the hot-rolled coil caused by the coil skid is prevented while ensuring the strength of the coil skid, to thereby inhibit the uneven hardness in the longitudinal direction of the hot-rolled coil resulting from this uneven cooling.
