The invention has for its object to offer a method using which a metal surface displays improved properties. These improved properties are in particular an improved flow of lacquer of the like over the surface, the adhesion of this lacquer to that surface and a general improvement in the lacquering and printing qualities of a metal surface.

Method for activating a metal surface

Method and device for handling ends for tins

A device for forming from a batch consisting of an undetermined number of more or less disc-like objects, such as metal covers, of a part batch consisting of a pre-selected number of objects, which device comprises a conveyor chute for supplying the batch of objects and for carrying them past a counting device for counting the passing objects and a separating device for separating off the batch when a pre-selected number of objects has been counted.

Device for forming a batch consisting of a predetermined number of discs

The invention relates to a device for packaging a row of covers placed coaxially of one another in a sheet of packaging material, comprising successively in the packaging direction: a feed station for the row of covers; a wrapping station for wrapping said row of covers in said sheet; a folding station for folding end wall and longitudinal fold edges of the sheet wrapped around the row of covers; and adhesive station for adhering fold edges to the packaging; and transport means for transporting the row of covers, which is characterized in that the folding station comprises gripping means gripping onto the wrapped packaging material from outside, which means hold the packaging material away from the row of covers during forming of the longitudinal fold. Preferably the device comprises an adhesive support which can move axially reciprocating relative to a row of covers present in the folding/adhesive station and accommodated in a sheet of packaging material and which forms a support for the longitudinal fold edges to be adhered. Tipping over of covers out of the row is prevented if further the adhesive support can move to a position P at an interval p from the row of covers, and that said adhesive support takes the form of a cylinder, the section of which corresponds substantially with that of said row of covers and which is provided with means for generating an underpressure in the space lying between said row of covers and said adhesive support, as a result of which a packaging constriction is formed. The invention relates further to rows of covers packaged in packaging material according to the invention.

Device for packaging a row of covers and the manufactured packaging

An apparatus is disclosed for packaging a row of mutually coaxially placed disc-shaped lids, in a sheet of packing material, comprising successively in the direction of progress of packaging: a feeding station for the row of members; a wrapping station for wrapping the row of members in the sheet; a folding station for the folding of the wrapped sheet; a sticking station for the sticking of the folded flaps to the package; further transportation members for transportation of the row of members; and a unit for supplying the packing material, situated between the feeding station and the wrapping station, characterized in that the feeding station is provided with at least two feeding units for the lids, and with a feeding table which is slidable between each of the two feeding units and the wrapping station. Preferably the transportation unit in the respective feeding unit detaches a row of lids from a given accreting row of lids, transports this detached row at increased speed through a certain distance into an intermediate station situated in the feeding unit, and brings it from the intermediate station to in front of the pusher.
