The apparatus includes an operating unit, which can be a welding unit for welding a closing film to an edge zone of a containing element or a separating unit for separating containing elements from portions of sheet material. The apparatus includes a control unit programmed to enable the operating unit to selectively process a continuous strip of containing elements or discrete groups of containing elements.

A method for manufacturing a wound dressing having a substrate, and a wound dressing manufactured by such a method are described. The method has a step of providing a sacrificial layer of material to be perforated by means of a hot pin perforator, in order to remove any molten residues on the heated pins of the hot pin perforator, before the same pins are used to make holes in the substrate. The presented method is cost effective, robust and reduces the risk of contaminating substances being embedded in the substrate during the hole making process.

Described is a process for introducing perforations in a laminate that comprises a silicone gel. The process includes the following steps: bringing an array of perforating elements in contact with a deformable layer of a laminate that at least includes a substrate layer, a layer comprising a silicone gel and a deformable layer, wherein said deformable layer covers said layer including the silicone gel; applying ultrasonic energy to said laminate in order to simultaneously introduce a plurality of perforations into said laminate, while providing deformed portions in said deformable layer, wherein said deformed portions penetrate into the plurality of perforations in said laminate; after having introduced said plurality of perforations into said laminate, keeping said deformable layer in contact with said layer including the silicone gel, such that said deformed portions remain penetrating into said plurality of perforations, for at least 12 hours.
