This method is the more recent and practical. It admits of one kind of sheet being sewn immediately after folding: nay, more: whilst one folder is still busy folding, another may begin to holländer. It is not till afterwards that the sheets are gathered. Gathered sheets are sewn in the same way, and are more easily knocked up than when sewn on cords and the threads left uncut after the old style instead of on metal bands. In holländert sheets the threads lie as shown in Fig. 18.

Lately, in brochuring, the sheets are not holländert, but sewn with wire on the machine. This is a very good method when the finest possible staple closing from the outside is used. For this work a small machine is used, similar to those used for wiring documents, copy-books, and single sheets, which have an automatic wire-drawing action.
The batch of sheets is here arranged face upwards to the right of the worker. The right hand takes the sheet by the head, opening it at the same time with the forefinger, and inserts it in the groove of the machine, which is at the same moment set in motion. With each different sheet the position of the staple must be changed so that all do not stand the same height, as it would cause the paper to be cut through in pressing.
The accompanying sketch shows the arrangement of the collected brochures.
