Abstract: The invention relates to a battery (10), in particular for a vehicle, having at least two battery cells (12) and at least one connecting element (16) that connects at least one electrical pole (14) of a first battery cell (12) to an electrical pole (14) of at least one further battery cell (12). The connecting element (16) includes plural individual wires (18) that are compacted in a respective attachment zone (20). The connecting element (16) is in contact with the respective electrical pole (14) of the battery cell (12) in the respective attachment zone (20). The invention further relates to a method for manufacturing such a battery (10).

Abstract: The invention relates to an opening cylinder (2) of an open-end spinning device as well as a fiber sliver opening apparatus with such an opening cylinder. In at least one lateral area (6) of the opening cylinder (2) a sealing surface for an air gap seal (12) is formed. According to the invention the opening cylinder (2) has an air passage (14) in at least the one lateral area (6), the output side of the air passage lying within the sealing surface or adjoining the sealing surface directly and the input side of which being at a shorter distance from the rotational axis of the opening cylinder (3) than the output side. During the operation of the fiber sliver opening apparatus, air is conveyed through the passages (14) to the air gap (12) of the air gap seal arrangement or conveyed past it, so that the entry of air and pollutants into the air gap (12) is counteracted.
