A method of manufacturing an evaporator includes: forming a length of tubing into a serpentine path, the length of tubing forming a tubing coil; forming a first evaporator plate; forming a second evaporator plate; positioning the tubing coil between the first evaporator plate and the second evaporator plate; bringing the first evaporator plate, the second evaporator plate, and the tubing coil into contact with each other; and forming a plurality of dimples in each of the first evaporator plate and the second evaporator plate, thereby at least partially crushing the tubing coil at a position of each of the plurality of dimples, a surface of each of the dimples contacting the tubing coil.

A cap of the press-twist type for a container, includes: a metal capsule having a transversal wall of longest extension which extends transversely with respect to an axis of the container, and a lateral wall; a curling in the distal part with respect to the transversal wall of the lateral wall by means of a curling operation; a sealing gasket with an annular shape for engaging with an opening of the container. The sealing gasket is made of a PVC-free material and includes a lateral portion, positioned in contact with the lateral wall of the capsule, which includes two portions away from the transversal wall of the capsule: a first distal portion relative to the transversal wall of the capsule and a second proximal portion relative to the transversal wall of the capsule, with a thickness greater than the first distal portion.

A metal closure for containers comprising a capsule designed to be applied to an opening of a container and including a circular part from which extends a perimeter edge. The perimeter of the edge has a rounding or folding obtained by curling and has a series of deformations made in a radial direction towards the centre of the capsule for forming the seal.

A peel-off lid with a rolled-in section around the extraction opening is formed in such a way that before forming the rolled-in section a thin plastic strip is applied onto the collar of the lid ring. After forming the rolled-in section, the plastic strip is melted in order to reach a good adhesion of the plastic on the upper side and the underside of the peel-off lid in the rolled-in section. In this way it is possible to reach a practically hermetic sealing of the cutting edge of the peel-off lid in an inexpensive way and with the possibility to manufacture with high cadence.

An assembly for feeding objects downstream into an automated machine includes a track, a tamping location on the track, a stop disposed at the tamping location, and a forward path through the track. A spring proximate to the tamping location moves between a first position and a second position. In the first position of the spring, the spring cooperates with the stop to interrupt the forward path. In the second position of the spring, the spring cooperates with the stop to open the forward path to allow objects to move downstream in the track.

One aspect of this disclosure provides a finger baffle for a heating furnace. This embodiment includes an elongated support plate having a length, and at least one finger baffle extending outwardly and in a vertically oriented direction from the elongated support plate. The at least one finger baffle has a width that extends along the length of the elongated support plate. The finger baffle may be employed in a high-efficiency gas furnace.

A tear-off lid with a curled edge of the removal opening is formed such that before the edge is curled, a plastics layer provided as a band of low thickness and preferably only 0.1 mm thickness is applied to the collar of the lid ring. In this way, a good seal of the cut edge of the tear-off lid is produced economically and with the possibility for production at a high rate.
