Abstract: This relates to the mounting of a mold for movement between a forming poson wherein a cup or container is formed therein with there being simultaneously applied to the formed cup a label, and a remote position wherein the mold receives a label. In the normal operation of the mold it is necessary that the mold be first moved axially to clear the newly formed cup and then pivoted to one side to a label receiving position for receiving the label. This particularly relates to the return movement of the mold from the label receiving position to the forming position wherein the movement is effected in a single step with the movement being a compound movement instead of the straight line movement followed by a pivotal movement of the mold as it moves from the forming position to the label receiving position thereby eliminating one separate movement step and thereby greatly reducing the time required to effect movement of the mold from the label receiving position to the operating position.

The mandrel is composed of stationary and rotatable parts relative to the forming chamber. The rotating parts coact with the curved or round parts of the forming chamber or mold cavity. The rotating parts include suction channels which bias the banderole thereagainst so as to effect an advancing movement of the banderole in the forming chamber. The suction channels are operatively connected to a vacuum source.

Abstract: This relates to a transfer apparatus for transferring labels from a label stack into the cavity of a moving mold half. The transfer device includes a pivotally mounted arm which has mounted on its free end a transfer head which swings about the arm so that for a limited movement of the arm there can be a much greater movement of the transfer head. Thus, the transfer head may rapidly enter and rapidly depart from a mold cavity so that a label may be seated in the mold cavity very quickly without requiring any slowdown of the movement of the mold half. The transfer head is provided with vacuum heads which operate to effect a peeling of a label from its associated stack beginning along one edge portion of the label so as to assure that only a single label is picked up from the stack.

The transfer head includes vacuum heads, one of which has associated with a suction cup thereof bellows for retracting the suction cup after the suction cup has sealed with the label to initiate peeling of the label from the stack. The suction cup is guidingly mounted so as to maintain its orientation at all times.

Abstract: A method is disclosed for blow molding poly(ethylene terephthalate) preforms, such as injection molded parison, to achieve exterior surface embossed designs on blown containers without using profiled blow mold cavity walls. In the method, a raised profile is molded or otherwise formed on the exterior wall of the preform, defining a preform wall portion having embossed areas. Then the entire preform is heated to blowing temperature and it is also disclosed that when the raised portion is at the same time raised to a higher temperature the embossed design of the preform is opacified by crystallization without crystallizing the balance of the preform. Thereafter, the preform is blow molded under conditions such that the poly(ethylene terephthalate) material strain hardens in order to cause the different wall thicknesses to expand and stretch essentially proportionately.

Abstract: A sign is fabricated which presents different messages depending on the angle of view. The fabricated sign has walls, different sides having parts of different messages. The method of fabrication includes taking at least two images, cutting them into strips of equal width and combining successive strips alternatively from the two images in order to form a third image, which is printed on a plastic sheet. This sheet is laid upon a wave-formed mold surface so that the tops of the waves coincide with the borders between the strips. The plastic sheet is softened and stretch-deformed, e.g., by vacuum deformation, while the borders are held against movement into the form of the waved mold surface.

Abstract: A method is disclosed for blow molding polyethylene terephthalate preforms, such as injection molded parisons, to achieve exterior surface indentations on blown containers without using profiled mold cavity walls. In the method, a profile is molded or otherwise formed in the exterior wall of the preform, defining a preform wall portion having sections of different thicknesses. Then, the preform is blow molded under conditions so that the polyethylene terephthalate material strain hardens in order to cause the different wall thicknesses to expand and stretch proportionately. As a result, the blown containers formed by this method include a surface contour which is essentially proportionately shaped to the surface profile formed on the pre-existing preforms.
