A long-handle film packing device includes a first rod and a second rod connected with each other. The first rod is formed with an axial limit groove. The second rod is provided with a limit member corresponding to the limit groove. Through the limit member limited to the limit groove, the length of the long-handle film packing device can be adjusted quickly. Through a positioning pin, the long-handle film packing device can be positioned quickly. The present invention can be applied to different lengths of packing film rolls. In addition, the packing film roll can be first mounted, and then the length of the film packing device is adjusted. Except that the length of the present invention can be adjusted and positioned quickly, the present invention has better practicability and convenience for installation.

Winder for an endless lane of a plastic web (2), with a revolving unit (6, 6, 55, 90), which is constructed so as to be rotatable about its axis (16) and has at least two winding shafts (10 to 12, 10 to 12) running parallel to its axis, onto which winding cores (17) can be loaded, then wound with the web (2) to a roll (18), finally unloaded therefrom again as finished rolls (18), wherein on both sides of the revolving unit (6, 6, 50, 90) support arrangements are arranged, in which the winding shafts (10 to 12, 10 to 12) are supported at their corresponding ends therein, and wherein the support for one end of the winding shafts (10 to 12, 10 to 12) is constructed so as to be detachable, such that the respective winding shaft (10 to 12, 10 to 12), with released support, can be loaded and unloaded from this end, characterized in that the detachably constructed support arrangements each have a gripper arrangement (36 to 38) with a two-armed scissor unit (39 to 41), the scissor arms (42, 43) of which surround the winding shaft (10 to 12, 10 to 12) in the closed position and are pivoted away therefrom in the open position.

A rolled graphite sheet includes a rod-shaped body and a graphite sheet having a length of 1 m or more and a width shorter than the length. The graphite sheet is wound around the rod-shaped body and is rolled in a length direction. When a length direction-end of the graphite sheet is pulled with a force of 1.5 N/cm in a direction parallel to a tangent of a cross-sectional circle of the rolled graphite sheet while fixing the rod-shaped body, the end moves 5 mm or less in the direction parallel to the tangent of the circle.

A system for active alignment of an inflatable web with respect to an inflation nozzle as the web is dispensed from a roll for serial inflation by the inflation nozzle, the inflatable web including top and bottom sheets sealed together by transverse seals to define a series of inflatable chambers having an opening between the terminal ends of the transverse seals and proximate a longitudinal edge of the web for receiving inflation fluid from the nozzle, the system comprising: a spool adapted to support the roll so that the roll rotates about the spool as the inflatable web is withdrawn from the roll; an actuator arranged to adjust the position of the roll along the length of the spool; an inflation nozzle adapted to provide inflation fluid into the openings of the inflatable chambers as the web travels along a path of travel past the inflation nozzle; a tracking sensor comprising: a sensor arm pivotally mounted at a pivot point at a given location relative the inflation nozzle, the sensor arm having a contact portion, the sensor arm adapted to pivot on the pivot point as the terminal ends of the transverse seals of the web contact the contact portion of the sensor arm; and an analogue sensor adapted to detect the movement of the sensor arm and to generate an analogue signal varying in relation to the movement of the sensor arm; and a controller operative to receive the analogue signal and based on the analogue signal to send output to the actuator to adjust the position of the roll on the spool to maintain the transverse position of the web within a predetermined range.

Web-wound rolls with a web edge treatment by printable adhesive compositions and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more quantities of adhesive are disposed and subsequent curing adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the adhesive.

An unwinding assembly comprising first and second unwinding and handling units comprising respective robots having respective wrists movable under the control of at least one electronic control unit, wherein each of said unwinding and handling units comprises a respective unwinding device mounted on the wrist of the respective robot. The present invention also relates to an unwinding and handling unit capable of handling the reel carried by it with high freedom of movement, while maintaining small dimensions.

A method for automatically replacing reels in an unwinding assembly capable of carrying out the handling operations of the reels, as well as preparing and joining the tail of the web of the finished reel with the head of the web of the new reel in a simple, efficient way, reducing the risk of malfunctions and maintaining the correct orientation of the new web as that of the finished web.

A plastic film applicator includes an applicator body including a mandrel and a grip connected to the mandrel, and a brake device including a bearing ring detachably mounted between the mandrel and grip of the applicator body for enabling the elastic braking pad to be biased toward the applicator body by an external force and an elastic braking pad having one end thereof connected to the bearing ring and elastically biasable by an external force. After the user attached a plastic film roll onto the mandrel of the applicator body, the user can press the thumb on the elastic braking pad to timely force the elastic braking pad toward the plastic film roll, forcing the abutment protrusion of the elastic braking pad into abutment against the film roll shaft, and thus, a braking effect is provided to the film roll shaft to stretch the extended plastic film for wrapping.

A waste disposal device has a container having an opening at a top end, the container defining an inner cavity accessible through the opening. A bag interface at the opening is adapted to hold a bag opened at the opening of the container with a closed end of the bag extending in the inner cavity. A pair of doors is pivotally connected to the container to open and close access through the opening and adapted to close off a portion of the bag passing therebetween, the doors being pivotable from a closed position in which the doors meet to close the access through the opening, to a first pivoted position in which the doors are pivoted away from the inner cavity. One or both doors is or are pivotable to a second pivoted position toward the inner cavity. An actuation mechanism biases the door(s) to the closed position.

The present invention provides a food wrapping film containing a thermoplastic resin, a blue colorant, and a polyglycerol fatty acid ester.
