For the purpose of attaching a strip of cloth provided with a zip-fastener component to a trouser forepart, first a rim of the strip of cloth and then the rim of the trouser forepart are folded over. The strip of cloth is arranged above the trouser forepart. Both folded-over rims are brought into a position relative to each other which they occupy after being joined together. Then they are brought into mutual contact and joined together with only a single seam in only one sewing operation. Thus very simple handling of the parts to be sewn together is achieved along with a very simple design of the required sewing units.
