A capping and de-capping apparatus for capping and de-capping tubes disposed in a tube holding rack having a two-dimensional array of apertures for holding the tubes. The apparatus comprises a rack support for supporting the tube holding rack, a head unit adapted for carrying a cartridge comprising at least one capping and de-capping gripper, a drive system for moving the rack support and the head unit relatively towards and away from one another, in order to cause engagement or disengagement of the capping and de-capping gripper with or from a cap of at least one tube, and a drive system for rotating the capping and de-capping gripper, wherein rotation in one direction causes attachment of the cap to the tube and rotation in the opposite direction causes detachment of the cap from said tube.

A chuck for a capping machine includes a plurality of chuck members, a biasing member configured to bias the plurality of chuck members radially inward, an abutting portion configured to abut against a top face of a cap, and a plurality of chuck jaws provided on an inner surface of each of the plurality of chuck members to engage knurls of the cap. Each of the plurality of chuck jaws includes a leading flank and a trailing flank. An angle of the trailing flank with respect to an outer circumference of the cap is less than an angle of the leading flank with respect to the outer circumference of the cap.

Methods of sealing a metallic container are provided. More specifically, the present invention relates to methods that reduce the amount of force applied to a metallic bottle to seal the metallic bottle with a ROPP closure. The methods include use of a capping apparatus that may include more thread rollers than known capping apparatus. Optionally, the thread rollers may use more forming passes to form threads on the ROPP closure. The capping apparatus may also rotate one or more of the ROPP closure and the metallic container in a closing direction before the metallic container is discharged. In one embodiment, the thread rollers form the closure threads before or after a pilfer roller applies a sideload to the ROPP closure.

An apparatus for automated capping and de-capping of test tubes having an ejector pin system for individualized cap ejection.

A device for assembling plastic objects including caps for coupling to base support at least partially counter-shaped to the cap. The device includes at least part of an assembly line defining assembly path and assembly plane including the assembly path and plurality of spindles moveable along the assembly path by an apparatus and configured to controlledly pick up the caps, the spindles position and push the caps onto the base supports along the assembly path; positioning apparatus including first and second detectors, controller with auxiliary control system to translate and rotate spindles along directions perpendicular to assembly path and plane and third encoder to detect spindle orientation relative to assembly path. First detector to detect first orientation, second detector to detect second orientation and controller to detect first orientation and second orientation by detectors and operate auxiliary control system to align base support and cap.

The present invention relates to a capping machine equipped with a plurality of capping heads with roto-translation movement. In particular, the present invention relates to a capping head (1) comprising a supporting structure (2) on which a roto-translation system (3) is mounted, operatively connected to a capping device (4), characterized in that the roto-translation system (3) comprises a linear motor (3a) and a rotary motor (3b) operatively coupled so as to impart a roto-translation motion to the capping device (4) and in that the capping head (1, 201) comprises a suspension system adapted to keep the rotary motor (3b) in a raised position even when the linear motor (3a) is disconnected or electromagnetically decoupled.
