Abstract: A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.

Abstract: An insect adhesive apparatus capable of automatically renewing an insect adhesive area and a control method thereof. The insect adhesive apparatus includes a roll rack, at least one motor, a camera module and a central control module. The roll rack is configured to equip a roll and unroll the roll to provide a long strip-shaped insect adhesive area. The motor scrolls out the roll on the roll rack according to a first control signal so as to renew the long strip-shaped insect adhesive area. The camera module acquires image information of the insect adhesive area. The central control module analyzes the image information to provide an area occupancy rate of attachments and determine whether the area occupancy rate of attachments is larger than a threshold value. If the area occupancy rate of attachments is larger than the threshold value, the first control signal is output to the motor.

Abstract: A tape splicing mechanism joins the tail of one tape to the leading edge of another tape. A frame defines a passageway along which the tape passes. A pair of arms rotatably attached to the frame have projecting posts and rotate between a first position where the posts are closer to the pathway and a second position where they are further from the pathway. The arms are urged toward the first position and a catch mechanism holds them in the second position until released by a release mechanism when a release indicia in the first tape passes. The leading edge of the second tape is looped around the first tape to form a loose knot and is tied to the post on each side of the first tape. When the arms are released they move to the second position and tighten the knot.

Abstract: The invention relates to a process and to a machine for splicing the trailing end of a running expiring web (e.g., a web of cigarette paper) to the leading end of a fresh web while the ends of the webs travel next to each other, in the same direction and at an at least substantially identical speed between a rotary knurling surface and a complementary second rotary surface which may but need not be a knurling surface. The rolls which constitute or mount the carriers for the two surfaces are driven in such a way that each n-th (e.g., each tenth) revolution results in the making of a splice between the leading and trailing ends of the webs. The forwardly and/or rearwardly extending remnants of the fresh and expiring webs are torn off the spliced-together webs at the respective ends of the splice.
