in fig5 therein the bills 47 of the front hooks 41 point rearward in the direction of fabric feed as indicated by the arrow 50 in a similar manner the rear hooks 42 are so arranged that a bill 48 of a rear hook 42 will cross and engage each rear needle 15 when the rear needle 15 is in its lower most position and in a well known manner to seize the yarn 22 and form a bottom pile loop therein the bills 48 of the rear loop pile hooks 42 point rearward in the same direction as the bills 47 of the front hooks 41 and the fabric feed 50 the spacing or gauge of the hooks typically corresponds to the gauge of the needles however it is possible for the gauge of the hooks to be a multiple of the needle gauge in which case not every needle would be threaded with yarn so that there would still be a hook to cross and engage each threaded needle it is also possible for the hook gauge to be a fraction of the needle gauge or stated differently for the needle gauge to be a multiple of the hook.
