Hook
The hook links the needle thread with the lower thread, thereby enabling the formation of stitches. Karl Friedrich Gegauf and his successors made lasting contributions to the improvement of hook technology. The CB (central bobbin) hook is characterized by an oscillating movement and relative resilience with respect to thread tension. By contrast, the rotary hook system, with which several artista models as well as the two newest models are equipped, is used in particularly high-end sewing machines, and boasts the advantage of an increased running speed and also the option of sewing 9mm zigzag stitches.The exclusive BERNINA patented design of the bobbin case allows for a more controlled sewing knot. With an extra thread guide integrated with the bobbin case allowing for less movement with lower thread during the process of the two upper and lower thread tying a knot.

Famous quotes containing the word hook:
“A hook shot kisses the rim and
hangs there, helplessly, but doesn’t drop
and for once our gangly starting center
boxes out his man and times his jump
perfectly, gathering the orange leather
from the air like a cherished possession”
—Edward Hirsch (b. 1950)
“And yet—it is not beauty that inspires the deepest passion. Beauty without grace is the hook without the bait. Beauty, without expression, tires.”
—Ralph Waldo Emerson (1803–1882)
“... with her shoulders as bare as a building,
with her thin foot and her thin toes,
with an old red hook in her mouth,
the mouth that kept bleeding
into the terrible fields of her soul . . .”
—Anne Sexton (1928–1974)
