Abstract
The invention relates to a shed forming device for a weaving machine, comprising two or more sets of hooks (2), which are provided with complementary hooks (2a, 2b) operating in conjunction with a pulley (40), the complementary hooks (2a, 2b) of one set of hooks (2) are operating in conjunction with one pulley (40) and a number of first pulleys (40a) of one or more first sets of hooks (20a) are provided in an upper row (100), and a number of second pulleys (40b) of one or more second sets of hooks (20b) are provided in a lower row (101). On the other hand, the invention relates to a weaving machine comprising a shed-forming device (1) as described above.
