Abstract: A self-compensating tension control device for regulating the withdrawal of filamentary material from a spool includes a fixed support that maintains an inverted cam surface and a spindle assembly rotatably carrying the spool. A tension force applied to the filamentary material, in opposition to a biasing force, moves the spindle assembly linearly in relation to the fixed support. A braking mechanism includes a brake drum rotatable with the spindle assembly, a friction band adapted to engage the brake drum and a rocker arm that engages the cam surface. When the tension force applied to the filamentary material is reduced and unable to overcome the biasing force, the cam roller engages the cam surface and causes the friction band to generate a braking force on the brake drum. Withdrawal of the filamentary material at a regular rate occurs when the biasing force is balanced with the tension force.

Abstract: A tension adjustment structure for fabric winding machine includes a driving mechanism, a roller, a fabric pressing mechanism and an adjustment mechanism. The roller and the driving mechanism have corresponding transmission wheels strode by a belt. The driving mechanism drives the roller to roll up a fabric. The fabric pressing mechanism has an action arm and a fabric pressing bar located on the action arm. The fabric pressing bar has a first position without in contact with the fabric and a second position in contact with the fabric and lifted by the fabric. The adjustment mechanism is butted by the action arm when the fabric pressing bar is at the first position to butt the belt and increase initial rolling force of the roller. The action arm releases the belt while the fabric pressing bar is at the second position so that fabric rolling tightness can be controlled.

Abstract: A brake structure of a band reel in a packing machine in which reliable braking effects can be obtained and responsiveness can be enhanced. A brake arm (15) has a coil spring portion (16) provided on one of its ends and a band passing ring portion (18) provided on the other end is mounted on one of ends of the reel shaft (13).

Abstract: A multiple coil dispenser supports a pair of coils for dispensing a flexible material from one of the coils. The dispenser includes a frame and at least one coil support for supporting the coils for rotation. A fixed arm is mounted to the frame and includes a plurality of rollers positioned longitudinally therealong. A movable arm is pivotally mounted to the frame for movement toward and away from the fixed arm. The movable arm has a plurality of rollers positioned longitudinally therealong and is biased away from the fixed arm. A bifurcated chute directs the strapping material from one of the coils to the arms. A brake assembly is operably connected to the movable arm between an engaged position when the movable arm is moved away from the fixed arm and a disengaged position when the movable arm is moved toward the fixed arm. A space between the fixed arm and the movable arm defines an accumulation region that varies in size as the movable arm moves toward and away from the fixed arm.

Abstract: A tape deck capable of simplifying a structure for obtaining a braking state is obtained. This tape deck comprises a brake member wound on a reel holder for holding the reel holder in a braking state, a swing member having a tension supply part for supplying a loaded tape with tension and a band pressing part for pressing the brake member thereby bringing the brake member into contact with the reel holder and a movable member coupled with the swing member through an elastic member. The swing member having the tension supply part is provided with the band pressing part for obtaining a second braking state (soft braking state), so that no additional component may be separately formed for obtaining the second braking state (soft braking state). Consequently, the number of components as well as the manufacturing cost are reduced.
