Abstract: A continuous filament (40) from a supply spool (50) is wound onto a takeup spool (52) in an amount to form one flat coil (54). A first winding device (42) forms a first flat coil (54) in winding space (36) between guides (28 and 30) while simultaneously a second winding device (44) winds a second flat coil in winding space (38) between guides (30 and 32) from the filament on the takeup spool (52). On completion of the flat coil winding, the guide (32), second winding device (44) and takeup spool (52) are removed from the shaft assembly (34), adhesive is applied to the newly formed flat coils and the coils along with guides (28,30) are moved onto spindle (90) and against a flange (92). The guides (28,30) are removed from the shaft assembly (34) adjacent the newly wound coils stored against the flange (92) and remounted next to the winding device (42).

Abstract: A novel roll loading mechanism is described which mechanically lifts a roll of web material into an operative position at the roll mounting of the printing press. This is accomplished by use of a dual chain conveyor having supports cantilevered from the chain, and synchronized to lift both ends of the core simultaneously to the printing press mount. This chain drive and the supports are selectively driven in a forward direction to lift the roll, and reversed to lower the roll to the initial pick-up position. A common drive shaft with sprockets to engage the chains is used to provide simultaneous and synchronized drive to the dual chain conveyors. A triangular configuration of the conveyor chain is used which presents an acute angle having its vertex above the press mount to assure secure position of the roll.

Abstract: Even in a case where increased taper winding is carried out by a yarn winding apparatus to form a cone, both end surfaces of a package is formed to be flat. In a cradle device for a yarn winding apparatus a swinging shaft of a cradle holder is inclined to an angle substantially equal to a taper of a conical bobbin with respect to a horizontal plane.

Abstract: A yarn build is applied to at a constant traverse length up to a limit diameter D. In order to achieve a uniform yarn draw-off tension, even with packages of large mass and correspondingly large diameter, the traverse length is thereafter reduced as the diameter increases. In the case of a conically shaped tube, the conicity of the build is also reduced which leads to improved exploitation of volume and greater package mass for a given package radius.

A second layer (50) overlies the first layer (42), the second layer (50) comprising a plurality of spaced-apart helical wound segments (52), with each pair of helical wound segments (52) being separated by a stepforward wound segment (54). The first and second layers (42 and 50) are wound such that the stepforward wound segments (54) of the second layer (50) overlie the helical wound segments (44) of the first layer (42), and the helical wound segments (52) of the second layer (50) overlie the stepforward wound segments (46) of the first layer (42).

Abstract: A yarn transfer arrangement in a yarn winding machine comprises two part-circular guide plates which , when an empty tube has moved to the winding position, move from a non-operating position, spaced apart on opposed sides of the winding position of the machine by a distance greater than the diameter of a full package, to an operating position in which the plates surround the empty tube apart from an entry aperture and an exit aperture allowing yarn travel to and from the empty tube. One guide plate causes the yarn to have sufficient wrap around the empty tube that, on operation of a cutter disposed on the other guide plate adjacent the exit aperture, the cut yarn end is entrained around the empty tube between it and the other guide plate, and winding of a package on the empty tube is thereby initiated. The guide plates are then moved back to the non-operating position.

Abstract: An improved mandrel for use in filament winding. Two embodiments are described for a new filament winding mandrel concept. The first embodiment comprises a plurality of spaced apart slots machined at an angle along the ends of the central mandrel section for use with machines of at least three degrees of motion. A second embodiment comprises a series of two circumferential rows of axial fins protruding along the circumference of the central section of the mandrel for use with machines having only two degrees of motion. A second configuration of the second embodiment is an addition of a strip of slots that are simply placed around and secured to the circumference of the mandrel at locations where fiber turn around is desired. This provides for fiber securing in place with minimal rather than requiring machining the axial fins into the tool.

Abstract: An elastomeric sleeve adapted to be mounted on a reel for winding strip into coil form has metal inserts adjacent a gripper slot opening for preventing flat spots in the coil. The sleeve is designed to permit sufficient expansion when the reel is expanded so that the gripper opening is not pulled apart and a widened gap is not formed therebetween. Preferably, slits are provided on the inner periphery of the sleeve for this purpose. Alternatively, a collar can be mounted on the outboard end of the segment bridging the gripper opening for enhanced structural rigidity to prevent the sleeve from pulling apart the gripper opening upon expansion of the reel.
