A labeling keeper including a protective sheet. The sheet is releasably attached to a backing sheet by adhesive and scored so that individual protector strips may be removed from the backing sheet. The protector strips are wrapped around an attachment member which holds the article to be identified such as a key. The attachment member is formed with an arm which holds the article. The protector strip when wrapped about the attachment member latches the arm so that the article cannot separate fro...

A machine for applying labels to the fin sealed ends of packages carried by a bucket conveyor in which the labels are cut from a web of printed roll stock placed on the fin seals and held in place by a hold down conveyor while the labels are folded by dynamic plows in conjunction with a series of guide bars.

A labeling machine has a rotor on which several oscillatingly driven pallet shafts are supported. Each shaft has a carriage shiftable transversely to the shaft axis. Glue pallets having partly cylindrical surfaces for being coated with glue are mounted to the carriage and are thereby movable from a radially outward position to a radially inward or neutral position for, respectively, contacting a glue roller and a label in a stack successively and for being retracted to neutral position out of th...

A labeling mechanism (10) for sequentially dispensing labels (49) from a backing strip (51) onto articles includes a pair of pinch bars (74) each having a knife edge (76) which bears against the rear edges of the labels (49) and downwardly against the backing strip (51) to move the labels along a pressure plate (66). The pinch bars (74) move in a linear reciprocating manner so as to push the labels (49) and backing strip (51) toward a labeling head (104) which also moves in a reciprocating manne...

A labeling device is described by means of which adhesive labels can be printed, dispensed, and applied on an article. During each operating cycle an adhesive label is printed in the device and transported into a dispensing position below an applicator roll which is mounted for rotation on an elastically deformable axle. In order to render the applicator roll yieldable to a degree desirable to make it conform to the surface to be provided with an adhesive label, the applicator roll is supported ...

The labeling machine comprises a stationary label hopper, a rotatable turret provided with suction means located adjacent to the leading edge of the terminal label in the article and constructed to enter into the hopper to lift by vacuum the leading edge of the terminal label out of the hopper and then in coaction with a pressure roll to mechanically withdraw the remainder of the label from the hopper and insert such leading label edge into the entry end of a fixed label guideway. Located interm...

A machine for labeling containers which are oriented vertically and have a bottom surface provided with a transverse jam recess that is at least partially radial to the longitudinal axis of the container. The machine includes a labeler and a work table moveable relative to the labeler. A plurality of plates are each mounted on the table for rotation about vertical axis and each plate includes a container supporting surface. A holder is disposed above each plate for vertical movement relative the...

A method for using an organic compound to label polynucleotides is described. The method utilizes an organic compound including an oligonucleotide, and electrophilic active site, an active complex, and a phosphate binding site. The oligonucleotide has a sequence that is complimentary to a specific region of a polynucleotide. This facilitates labeling of DNA or RNA at a specific site in its sequence. The active site consists of a stable precursor, and only becomes reactive upon activation. Leavin...

The invention provides a labeling machine comprising a structure, a labeling head capable of pivoting relative to the structure about a pivot axis, the labeling head being fitted with gripper means for gripping a label holding it in a plane that is substantially normal to the pivot axis of the labeling head, and placing means carried by the labeling head and adapted to take the label held by the gripper means and place it on an article to be labeled that is present on the labeling machine. Accor...

A device for applying a label to a disc includes a support member, preferably in the form of a plate for supporting a label on its upper surface, the plate having a central opening through which projects a disc positioning member, for example, in the form of a rod and a carriage member, preferably in the form of a plurality of bearings mounted on resilient arms. The bearings are adapted to move under pressure from above from a first position in which the bearings project upwardly through the ope...
