Abstract: A mechanism for engaging a resting bobbin 10 carrying a web of packaging material and raising it into a rotatable web withdrawal position. A pair of bent yoke arms 17,18 straddling the bobbin carry lateral clamping jaws 14,15 at their one ends. Their other ends are movably pivotally mounted to a plate 11 by a pair of support plates 29,30 and a pair of lifting plates 25,26, the latter being eccentrically coupled to meshing drive gears 20,21. The continuous rotation of the gears successively pivots the jaw ends of the yoke arms inwardly to engage the bobbin, and thereafter raises the arms and bobbin into the working position.

Abstract: In a veneer assembling machine in which an adhesive thread is adhesively applied over the joint between two strips of veneer, a spool (26) is detachably secured to a machine base plate (27) in a receiving ring (31). A ring shoulder (28) engaging in the receiving ring (31) at the end of the spool (26) is thus provided with sliding tracks (29) and with adjacent indentations (30) in which a machine end stop pin (38) engages. A thrust ring (33) is resiliently mounted in the receiving ring (31) and presses against the ring shoulder (28) from below and tensions the spool (26).

Abstract: A method of, and apparatus for, taking-off a thread or the like alternately from one of two bobbin packages arranged side by side in a creel for textile machines. The method contemplates taking-off a thread from a bobbin package, the tail end of such removed thread being knotted to the lead end of an essentially parallelly arranged reserve bobbin package. The knot is formed by first pulling the leading thread end of the reserve bobbin package through a thread take-off opening operatively associated with such reserve bobbin package. Then the thread is pulled in a direction opposite to the thread take-off direction through or at a location near a take-off opening operatively associated with the bobbin package from which thread is in the process of being removed, in other words the momentary withdrawal bobbin package.

Abstract: A holder for paper towels and the like. A standard extends from the side of a flat base and is integral therewith. A major portion of the standard comprises four radially outwardly-extending strips extending out at ninety-degree intervals from a common center, the outer edges of all strips tapering together outwardly from a widest portion at the base. A minor portion distant from the base comprises an extension of each of the four strips, with them separated from each other at the center by a gradually increasing amount. The strips can be forced in toward the center with springy resilience tending to restore them to a normal outward position. Each strip terminates at an out-turned finial.

Abstract: A spool for thread or the like is provided with means for locking or securing the spool in position over a spindle. The spool may be of the type having a base member and a substantially cylindrical portion in which the thread may be taken from the spool in a direction substantially parallel to the spool axis. A locking means is provided to prevent spool jumping when the thread on the spool is partially removed making the spool with the remaining thread thereon lighter. In one embodiment, radial score marks, indentations or grooves are formed in a thin membrane section of the spool formed across the bore of the spool. The spool is designed so that the thin membrane will break along the radial score marks when placed over the spindle with the inwardly pointing ends of the thin membrane engaging the spindle thereby holding the spool down. In another embodiment, an adhesive is provided on the bottom of the base portion of the spool to temporarily fasten the spool to the thread stand plate.

Abstract: A yarn package positioning device for textile machines such as shuttleless looms for selectively locating the weft yarn package support spindle in the most advantageous location for withdrawing weft yarn from the package carried thereon during insertion of the weft into a warp shed. Additionally to facilitate and simplify replenishment of the weft supply the support spindle is mounted on the positioning device so that it can be manually pivoted between a donning and doffing position and the preselected position for withdrawing the weft from the yarn package.

Abstract: Cop tube holder for winding yarns or threads on textile machines, and more particularly on open-end spinning machines with an automatic cop exchange, provided with a pair of bent levers adapted to swing in the holder and carrying rotatable dishes for placing the front portions of the tube while the operating pressure necessary for clamping a tube between the dishes is exerted by a spring. The bent levers are motion-coupled to each other by means of a kinematic pair.

Abstract: A magazine apparatus adapted for presenting run off spools to a rewinding machine comprising a drive mechanism, a rotating means driven by said drive mechanism, a plurality of free hanging arm means pivotally connected to a said rotating means and a spool support plate connected to said free hanging arm means for supporting the spools during presentation to the machine. According to a preferred embodiment, the rotating means comprises a single bar but also disclosed are embodiments in which the rotating means comprises a three pointed star or a disc means. The rotating means is driven in a plane that is parallel with respect to the pull of gravity. The free hanging arm means and the associated spool support plates are adapted to maintain the spool in an upright position during the entire course of rotation of the rotating means. The disclosed apparatus is relatively simple in structure and allows a machine attendant to swiftly and easily replace exhausted spools.

Abstract: An arrangement for fastening in place yarn bobbins in looms, in which a support member fastened to the loom plate holds a shaft member at an inclined angle. A lower ring-shaped bobbin holder passes over the shaft member and supports the lower end of a bobbin held on the shaft member. The lower bobbin holder is freely axially movable on the shaft member. A spring is disposed between the shaft support and the lower bobbin holder. The bobbin is held in place at the upper end by a replaceable ring-shaped member having a predetermined taper to accommodate bobbins of various diameters, lengths and shapes. A locking ring bearing against a projection on the free end of the shaft, holds the bobbin together with the lower and upper retaining rings in place on the shaft. Spacers are applied on the shaft between the upper replaceable ring and the locking ring, as required, to accommodate bobbins of varying lengths.

Abstract: An assembly for supporting a conventional bobbin having at least one metallic ring about its base. A pair of spaced plates define a first groove for receiving the ring on one side of the bobbin. A movable plate member is provided at its bottom portion with a second groove. The latter groove is defined by a flange on the plate member and an L-shaped member secured to the plate member. The plate member is spring biased towards the spaced plates whereby the bobbin ring is received within the second groove on the opposite side of the bobbin. The retention of the ring in the grooves prevents the bobbin from being lifted from the assembly.
