Abstract: An improvement in the wrapping of successive articles in heat-sealable film supplied in a continuous length to an elongated generally tubular former which progressively wraps the film around the sides of the articles and seals the margins together while air is being evacuated from the interior of the wrapping material comprises the provision of a lengthwise slot in the tubular former and placing the vacuum supply pipe outside the former and near the slot so that the articles do not ride on, or come in contact with, this supply pipe. In the preferred form the margins of the film are sealed along a continuous line outside the supply pipe and along a discontinuous on the other side of the pipe so that air evacuation can take place.

Abstract: A container for delicate articles which includes an inner envelope, and an inflatable outer envelope sealed to the ends thereof. The inner envelope is vented to the exterior of the container so that, on inflation of the outer envelope, the inner envelope is collapsed tightly about the article, which is thus suspended in and protected by the inflated outer envelope. Preferably, the inflation is accomplished within an outer protective casing, which is coated on its interior with an adhesive. Should the casing and outer envelope be punctured, the parts will then still be kept in essentially established positions.

Abstract: Apparatus for forming a hinged or clamshell type carton from a paperboard blank includes a carton forming die for receiving the paperboard blank, a movable frame for transferring the carton blank from the stack into registration over the die, and a reciprocating plunger mounted above the die for forming the carton. The blank is formed into a finished carton in one simple harmonic motion. The movable frame includes a number of vacuum assisted suction cups for lifting the carton blank from the stack and at least a pair of gathering rollers which cooperate with a pair of pivoting blades mounted adjacent the die to fold and gather the hinge of the carton blank as the blank is positioned and pressed into contact with the die. A pair of inverted "T" retaining bars, disposed on the die adjacent the carton hinge, prebreak glue tabs on the carton and capture and retain the wall panels of the carton when the blank is pressed into registration with the forming die.

Abstract: Filamentary members, music strings for example, are automatically coiled and the coils captured on a sheet of packaging material by feeding the members into an annular groove against a surface of a sheet of heat sealable material and subsequently shearing tabs from the sheet of material and folding the tabs over the coiled member. Coiling of the members is accomplished by feeding a first end of each member, preferably with the aid of pneumatic pressure, into the annular groove, capturing the end in the groove and thereafter causing relative rotation between the groove and member to draw the member into the groove.

Abstract: Conventional heads for screwing bottle closures on to bottles generally are applied to the closure cap, while rotating at full speed which causes tipping of and damage to the closure cap. The invention seeks to overcome this disadvantage by a sleeve portion at the bottom of the fitting head first being applied without any torque to the closure cap, the sleeve portion being force-lockingly engaged with the rotating head only when the head is moved further downwardly through the clutch-engagement distance. When a maximum torque, which can be adjusted by means of a stressing spring, has been reached, the clutch begins to slip and the sleeve portion stops. The sleeve portion is of low mass so that after disengagement of the clutch, no additional torque due to inertia is applied to the closure cap.

When the bottle-shaped containers thus conveyed are aligned in predetermined longitudinal and lateral arrary in predetermined number to be stood by, they are simultaneously held by the bottle-shaped container group holding mechanism utilizing negative pressure, and are then raised from the standby position.

Abstract: End closures for cans fed horizontally at given intervals at a high speed are shifted in direction, one after another, to be substantially perpendicular to a support passage extending substantially horizontally, received separately by the passage rapidly and positively, and lotted out when a predetermined number has been reached by the pieces received. Each lot thus compacted to a solid cylindrical form is put into an elongate paper bag, and the open end of the bag is closed.

Abstract: A method of vacuum packaging compressible material in a sealed flexible fluid impervious container, such as a poly bag, is disclosed. One or more slits are made in the container and air in the container is withdrawn through the slits. This creates a partial vacuum in the container that results in compression of the compressible material. When the desired compression has been obtained, restraining means are placed around the flexible container to maintain the package in a compressed state when the partial vacuum is eventually lost. A novel apparatus for use in this method is also disclosed.
