Abstract
The apparatus (1) is used for forming a ball of yarn. It contains a container (2) having an internal volume (21) which is outwardly bounded in the vertical direction partially by an internal wall (31) and in the horizontal direction completely by the internal wall (31). The internal wall (31) has an inlet opening (41) through which the yarn is injectable into the internal volume (21) by means of an air flow. The internal wall (31) is rigid. The internal volume (21) has a downwardly open outlet opening (22) for a yarn ball formed in the internal volume (21). A lower part (33) of the internal wall (31) is inclined downwardly towards the outlet opening (22). By virtue of the rigid construction, the apparatus is simple and cost-effective. Possible problems with moving parts are avoided.
