A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has holding mechanisms each having a shaft that holds a film roll, a holding mechanism support frame supporting the holding mechanisms, a moving mechanism that rotates the holding mechanism support frame to move each holding mechanism between a film roll setting position and a film supply position, a splicing mechanism splicing a trailing end portion of the film of the roll of one of the holding mechanisms and a leading end portion of the film of the roll of another one of the holding mechanisms, and a film drawing mechanism that rotates the shafts of the holding mechanisms to draw the film independently from the film rolls attached to the shafts of the holding mechanisms and changes the drawing speed of the film during bag-making and packaging.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

An apparatus, system and method for providing an automated contact cutter. The contact cutter includes a contact reel holder for holding therein a bandoleer comprising a plurality of stamped contacts; at least an inlet roller comprising an inlet pin, a turn roller, and a receiving roller mechanically connected by at least one motor drive belt to a drive motor, wherein the inlet roller is capable of receiving an end portion of the bandoleer onto the inlet pin for loading; a cutter between the turn roller and the receiving roller that is capable of cutting ones of the stamped contacts from the bandoleer for picking by a pick and place robot; and a comb capable of combing at least the bandoleer and cut and partially cut ones of the stamped contacts.

An automatic document feeder includes a media path to route media through the automatic document feeder, a plurality of opposing roller pairs to route media along the media path, and a serpentine belt drive system to drive a roller of each of the opposing roller pairs.

The present invention relates to the technical field of optical film production, and provides a light guide film production device, including a feeding unit, a fusion stirring unit, an extrusion molding unit, a cooling shaping unit, a guide leveling unit, a flattening unit, and a finished product winding unit. The cooling shaping unit is provided with a first water tank to perform heat exchange on an extruded light guide film for heat recovery, so that edge film pressing mechanisms press pressure blocks at the edge film positions using the memory effect of a memory alloy. Circulating water of the first water tank subjected to heat exchange is delivered to a second water tank disposed in the flattening unit, so that a first conveyor belt made of the memory alloy in a third drive device drives a second rolling roller set to rotate to realize secondary utilization of recovered heat. In the present invention, an air delivery mechanism with one airflow pipe to the cooling shaping unit, and the other airflow pipe to the flattening unit is further provided. According to the present invention, the heat of the light guide film production process is used to improve the quality of the light guide film and reduce the energy consumption of the light guide film production process.

The present invention relates to Indexer table (1) for rotary and horizontal shifting of paper bunches. Said indexer table (1) having spider arms shifted in rotary manner through pinion gear and servo motor. The drive power is provided to auxiliary shaft (5) from main shaft (4) through the pulley (11) and belt (19d) configuration. The juxtaposed shafts receive the drive power from the auxiliary shaft (5) through universal joints (10). The cam (12) on each shaft rotates along with rotation of the shaft for reciprocal movement of spider arm (20). The actuator (13) actuates follower (13b) for open and close movement of bunch gripper (21). Said bunch gripper (21) grips bunch paper and then said driven shaft (14) rotates so that the spider arm (20) shifts bunch paper in rotary manner. After performing operation of bunch paper, the spider arm (20) shifts bunch paper to next platform.

A mobile hose reel assembly (100) includes a housing (110). The housing (110) includes a first wall (112), a second wall (114) coupled with and disposed opposite to the first wall (112) and a handle portion (116) coupled with the first wall (112) and the second wall (114). The housing (110) further includes a hose reel module (120) housed within the housing (110). The hose reel module (120) includes a hose reel (122), a drive motor (124) operatively coupled to the hose reel (122) and a transmission mechanism (126) adapted to transmit the motion of the drive motor (124) to the hose reel (122). The mobile hose reel assembly (100) is characterized in that the hose reel module (120) is adapted to exhibit a rocking motion relative to the housing (110). Further, the drive motor (124) is selectively activated and deactivated based on the rocking motion of the hose reel module (120) relative to the housing (110).
