摘要： Mit Hilfe des Verfahrens wird eine Ware mit einer Folie umwickelt. Die Folie wird von einer Vorratsrolle abgespult und über mindestens eine Umlenkvorrichtung der Ware zugeführt. Die Ware beaufschlagt die Folie mit einer diese von der Vorratsrolle abspulenden und sie dehnenden Kraft. In einem Bereich zwischen der Vorratsrolle und der Umlenkvorrichtung wird die Folie vorgedehnt und in einem Bereich zwischen der Umlenkvorrichtung und der Ware nachgedehnt. Sowohl die Vorratsrolle als auch die Umlenkvorrichtung können gebremst werden. Die Ware wird bezüglich einer sich im wesentlichen senkrecht zu einer Transportrichtung der Folie erstreckenden Drehachse rotatorisch angetrieben. Die Vorrichtung zum Umwickeln der Ware mit einer Folie weist eine die Folie bevorratende Vorratsrolle und mindestens eine rotationsfähig gelagerte Umlenkvorrichtung auf. Im Bereich der Vorratsrolle ist eine Vorratsrollenbremse und im Bereich der Umlenkvorrichtung eine Umlenkvorrichtungsbremse angeordnet.

摘要： Eine Wickelrollenlagerung besteht aus zwei an einem Maschinen­gestell (1) befestigten Tragarmen (2) mit nach oben hin offenen Lager­schalen (3), die Lagerflächen in Form von etwa mittig geteilten Hohl­zylindern aufweisen. Um eine Wickelrollenbremse zu schaffen, die die Wickelrollenwelle (5) mit gewichtsproportionaler Bremskraft ab­bremst, bestehen die Lagerflächen aus einer Schicht aus Vulkollan (4) oder einem anderen Material mit ähnlich guter Abrieb­festigkeit und ähnlich hohen Reibwerten -.

摘要： An apparatus for controlling the amount of delivery in a wrapping material feed system, including a rotation drive means for rotating a bobbin with a wrapping material wound thereon; a winding diameter detecting means for detecting a winding diameter of the wrapping material; an adjusting means for changing torque and brake forces of the bobbin to adjust the amount of delivery of the wrapping material, and a control means for controlling the adjusting means. The control means has a memory section which stores optimum torque and brake forces for winding diameters of the wrapping material as well as increment and decrement patterns of torque and brake forces for various operation modes of the wrapping material feed system, and upon receipt of a signal from the winding diameter detecting means the control means provides a signal to the adjusting means in accordance with the contents of the memory section.

摘要： A machine (1) for wrapping food products (P), e.g. ice cream products, comprises at least one reel holder arrangement (200) for supplying a web (10) of wrapping material from a reel (201) of rolled-up wrapping material. The reel holder arrangement (200) comprises a rotatable reel holder for holding the reel (201) such that reel holder is driven to rotate by the machine (1) drawing the web (10) from the reel (201), and a brake module (202) which operable to apply a brake force to a shaft of the reel holder. A control unit (20) is arranged to generate, based on a measured or otherwise known web infeed rate (S in ) of the machine (1) and a measured rotational speed (ω m ) of the reel holder, a control signal (C1) for operating the brake module (202) to set the brake force so as to control tension in the web (10). The machine (1) may be a multi-lane wrapping machine with a plurality of reel holder arrangements (200).

摘要： A manually-operated dunnage conversion apparatus includes a housing with an outlet opening, a supply of slit sheet stock material supported within the housing for dispensing from the outlet opening, and a pair of opposed expansion members rotatably coupled to the housing for rotation about respective, parallel expansion axes between the supply and the outlet opening. The expansion members are biased towards each other via a biasing member to provide a gripping force on sheet stock material fed therebetween to apply friction to the sheet stock material that causes the sheet stock material to expand in length and thickness as an operator pulls the sheet stock material from the outlet opening in the housing. With the possible exception of the biasing member, the apparatus may be made of paper-based products, making the apparatus recyclable, reusable, and composed of a renewable resource, as well as inexpensive to manufacture.

摘要： A control system (42) for controlling operation of main and secondary drive units (22, 34) in a web winder system (10) to provide tension control of a continuous material web (12) is disclosed. The control system (42) causes the main drive unit (34) to operate in a velocity mode to set a linear velocity of the continuous material web (12). The control system (42) receives inputs from tension and speed detectors (44) in the web winder system (10) that detect a tension and speed of the continuous material web (12) and causes the secondary drive unit (22) to operate in a modified torque regulated closed-loop tension control mode so as to control a tension in the web material (12), with the control system (42) causing the secondary drive unit (22) to operate according to a torque regulated closed-loop tension control mode and integrate a speed feedback loop into the torque regulated closed-loop tension control mode so as to introduce active damping into the tension control.
