The earlier invention "A BOBBIN HOLDER" comprised of : 1) 'A Reliable Operating Mechanism' having retractable fingers to hold and release the roving bobbin or an empty tube, which is done manually or by mechanical bobbin changing apparatus. 2) 'A Bearing Mechanism' consisting of balls, to perform a smooth rotation with a slight swing operation. 3) 'An Internal Brake Mechanism' to apply a constant friction, to perform a uniform delivering of yarn. This brake mechanism is of a single brake force system. The principle of the Internal brake mechanism is to create a constant friction on the outier surface of the head during Its rotation. The internal brake mechanism consists of a brake shoe (16), which is having a profile that of the head (2). Over the brake shoe (16), a brake spring (13) is placed. When the brake spring Is compressed, a load is applied on the brake shoe (16). The free length of the brake spring, when deflected to a particular height, a compression load is applied on the brake shoe (16), so a friction is created to the head during Its rotation. It is an objective for the present new invention, to provide 'A BOBBIN HOLDER" with "MULTI BRAKE SYSTEM". The internal brake system of "A BOBBIN HOLDER WITH MULTI BRAKE SYSTEM" facilitates the selection of various brake forces in one Bobbin Holder. It is yet an other objective of the invention to facilitate the Bobbin Holder to change the required brake force without removing the Bobbin Holder, which is suspended from the triangular metal section (11) in the creel of the textile machine. 'A BOBBIN HOLDER WITH MULTI BRAKE SYSTEM" is capable of applying various loads over the brake shoe (16), which creates friction to the upper surface (2c) of the head, during its rotation. ""A BOBBIN HOLDER WITH MULTI BRAKE SYSTEM" consists of a cap (14) with two pairs of leg. The legs of a pair are placed opposite to each other at 180°. Of the two pairs of leg, one pair is taller (14 a) and the other pair is shorter (14 b). A rib (14c) is provided on the outer wall of the cap along with each taller leg (14a). The taller legs are capable to locate into the slots having symmetrical heights of the Indicator (25). "A BOBBIN HOLDER WITH MULTI BRAKE SYSTEM" also consists of an Indicator (25). The two taller legs of the cap and the top portion of the cap will be rested into the Indicator. The indicator (25), having various slots with depth of various symmetrical heights (symmetrical heights are opposite to each other), allows the two taller legs (14 a) of the cap to rest In it. When the taller legs (14 a) are rested in slot (25b), the rib (14c) provided on the outer side of the cap along the taller legs, will point to the appropriate number provided on the face of the Indicator (25). "A BOBBIN HOLDER WITH MULTI BRAKE SYSTEM", also consists of a cover. The cover is placed on the indicator, so as the supports of the cover which is provided inside is close to the upper outer wall (25a) of the indicator. According to the present invention of the "BOBBIN HOLDER WITH MULTI BRAKE SYSTEM", the selection of required brake force shall be done by simple operation. It is facilitated by pulling the cap downwards and rotated slightly to the right for the next ascending number for the increased position of brake force. The rib (14c) of the cap will be pointing to the appropriate number and as well as to the corresponding colour on the cover (24), at this position the cap is left free. The taller legs (14a) of the cap now slide into the slots simultaneously. At this position the brake spring is compressed, thus a load is applied on the brake shoe which creates friction to the head during rotation. For every increased position of brake force (from 1 to 4) the same steps are followed. Correspondingly, for every reduced position of the brake force, the same type of steps shall be followed, by rotating the cap to the left after pulling It down. However, from the 4th position of the brake force, if the cap is pulled downwards and turned to the right further, it is pointed to the first position again and when turned to the left, it points to the 3rd position of the brake force. Typical steps can be followed to select appropriate brake force as per the requirement.
