摘要:
The stopping of a winder is controlled such that winding is stopped when a desired length of a web has been wound on a roll being formed/unwound from a roll being formed or when the size of the diameter of the roll is desired. An estimated stopping length is calculated based on speed, acceleration and a desired end speed.

The rewinding machine comprises a winding roller (5) equipped with a moving axis to remain in contact with a log (R) being formed and allow the diameter of said log to increase. A member to control the action of said roller on the log (R) being formed is associated with the winding roller with moving axis. The control member is provided with a stop position that can be set to be reached before winding of the log (R) is completed. Winding of the log being formed is essentially completed without moving the axis of the winding roller with moving axis (5) in order to obtain a finished log always with a more or less constant diameter.

The present invention provides a web splicing method and a web splicing apparatus with which a line velocity on an output side of the splicing apparatus does not fluctuate through a web splicing operation. The method and apparatus are further operable to maintain a line velocity at a predetermined velocity after the web splicing operation. The method of the present invention includes the steps of: connecting a second web Wb fed out from a second roll B to a first web Wa; cutting off the first web Wa at a position between a point at which the second web Wb is connected to the first web Wa and a first roll A; spinning the second roll B to feed out the second web Wb; obtaining a value of a diameter of the second roll B based on a state of an accumulator 4; and controlling a circumferential velocity of the second roll B based on the obtained diameter.

A system and method for splicing reeled media using operational feedback. According to certain embodiments, the method of operating a media production system involves sensing speed parameters of first and second reeled media, tracking an unwinding parameter of the first reeled media, and positionally tracking a leading end position of the second reeled media. The method also involves controlling splicing between the first and second reeled media based at least partially on the speed parameters, the unwinding parameter, and the leading end position.

A fully-integrated computer-aided method for sizing and building paper reels from which a plurality of smaller rolls of paper are created. Data pertaining to the measurements of paper reels and the rolls to be built therefrom is entered into a computer programmed with electronic spreadsheet software, which stores, validates and computes measurement values so that the diameter of the paper reel from which the smaller paper reels are being built is of the correct size to minimize waste.

A label applicator of the type for separating labels from a continuous carrier strip and applying the labels to an object positioned at the applicator, includes a tamp pad for receiving the label at a first position and contacting the label to the object to apply the label to the object when the tamp pad is at a second position. The tamp pad operably connected to a tamp pad cylinder having a compressed gas inlet for extending the cylinder and a compressed gas inlet for retracting the cylinder. A pressure transducer is in communication with the compressed gas inlet for extending the cylinder and measures pressure in the cylinder. A controller controls movement of the cylinder between a retracted position for receiving the label and an extended position for applying the label to the object. The controller receives input signals from the pressure transducer for returning the tamp pad from the extended position to the retracted position.
摘要:
A winding mechanism for winding a narrower web has a drive shaft with a torque transmitting member fixedly mounted thereon, and a holder rotatably mounted on the drive shaft with a spring disposed around an outer circumferential surface of the holder with cushioning members interposed therebetween. Stoppers are disposed respectively in three chambers defined in the holder. A groove is defined in an inner circumferential surface of a winding core around which the narrower web is wound, and the cushioning members are fitted in the groove. A pressing force of the spring is applied through the stoppers to the winding core which is mounted on the holder.
摘要:
A label applicator is of the type for separating labels from a continuous carrier strip and applying the labels to an object positioned at the applicator. The applicator includes a frame, a supply roll operably mounted to the frame for supplying the carrier strip having the labels thereon and a separator for removing the labels from the carrier strip. The applicator includes a rewind roll operably mounted to the frame for rewinding the carrier strip after the labels have been removed therefrom. The supply and rewind rolls are configured to move the carrier strip through the applicator. A rewind assembly has a motor, a pivoting arm and a sensing assembly cooperating with the pivoting arm. The sensing assembly is adapted to sense the presence or absence of a sensed element mounted on the pivoting arm as the arm moves from a first home position to a position other than the home position. The sensor is operably connected to the rewind roll motor to actuate the motor upon movement of the arm away from the home position.
