Abstract: An in-mold label dispenser for a blow molding machine having a dispensing head mounted on a base for movement along a first path from adjacent a label magazine to between the open sections of a mold. The label carrier is mounted on the dispensing head for movement along a second path substantially transverse to the first path from a retracted to an extended position. A drive mechanism is mounted in the base for moving the dispensing head along the first path and the label carrier along the second path in co-ordination with the opening of the mold. An adjustable stop assembly is provided on the label carrier for stopping movement of the label carrier along the second path after the label carrier has moved a sufficient distance into the mold section to establish a gap of predetermined width between the label and the wall of the mold cavity.

Abstract: A system for identifying the origin of a plastic bag made from web stock on a machine having a plurality of bag making stations wherein each station has a vacuum port for holding the web stock to the station during the bag making operation and each vacuum port has an identifying characteristic which is impressed in the web stock to identify the work station.

Abstract: A hot wire has one end mounted on a pivotally supported arm which is biased to keep the wire straight and taut. The end of the wire is bent to an L-shape and is rigidly attached to the arm. Between the bend and the point of attachment, the wire is formed with a flexible portion which expands and contracts to compensate for pivotal movement of the support arm.

Abstract: Apparatus for making bags from a folded web of thermoplastic material includes a rotating drum to which the web is continuously applied. As the drum rotates through a given arc length, the web is tucked outwardly from the periphery of the drum in progressively deeper folds wherein the depth of tuck determines the width of the bag. A cam, controlling the depth of tuck is movable in a rectilinear radial direction for adjusting the depth of tuck, thereby controlling the bag width.

Abstract: A lining to be applied to a spine of a book is disclosed wherein the lining is characterized by an integrated construction of a tough, relatively lightweight, durable, synthetic sheet exhibiting dimensional stability, good printability and good ink adhesiveness and which has printed simulated headbands at its opposite ends. The lining has a maximum length corresponding to the length of a book spine to which the lining is to be applied and the extent of the printed headbands correspond to the thickness of the book to which the lining is to be applied.

Abstract: In making integrated linings to be applied to spines of a succession of books in a bookmaking process, a high speed low cost method is disclosed which includes feeding strip stock from a supply of lining material, printing simulated headbands on one surface of that strip adjacent its longitudinal side edges and cutting the strip transversely to its longitudinal axis to form a succession of individual linings to be applied to spines of a succession of books.

Abstract: A printing mechanism is disclosed in a high speed apparatus for making low cost integrated linings to be applied to a succession of books being conveyed through a bookmaking machine. The printing mechanism is supported on a frame in a feed path of strip stock for printing simulated headbands on one surface of the strip, and a cutter is operatively supported on the frame for cutting the printed strip transversely of its longitudinal axis into individual linings to be successively applied to books being conveyed through the machine.

Abstract: Apparatus and method for the dry forming of fibrous pads employ a pad forming member closing the lower end of a pad forming area. The pad forming member preferably is in the form of a condenser roll having three-dimensional pockets, or cavities about the periphery thereof. Each cavity includes an opening into it, and the cavities are brought into communication with the pad forming area as the condenser roll is continuously driven during operation of the apparatus. Each cavity is defined by foraminous bottom and side surfaces, the surface area of which is greater than the surface area of the opening into it. An air suspension of fibers is formed in the pad forming area, and a vacuum is applied through the foraminous surfaces of each cavity when it is disposed in the pad forming area to pull the air of the suspension through the foraminous surfaces, and deposit the fibers carried in the air suspension onto the foraminous surfaces in the form of a fibrous layer.
