A processing line processes logs of convolutely wound web material and has upstream and downstream sections. A main accumulator has buckets that receive, hold, and release logs. An input feeder receives logs from the upstream section and conveys them to a bucket of main accumulator. A loader has a loader accumulator and loader buckets that receive, hold, and release logs. A transfer conveyor between the main accumulator and the loader receives a log from the main accumulator bucket and conveys the log a loader bucket independently of the input feeder. The loader receives a log from the transfer conveyor. The loader conveys the log in the loader bucket to a discharge of the loader. The loader discharge discharges the log from the loader bucket to the downstream section of the processing line.

There is described a magazine unit for a packaging machine comprising an inlet opening configured to allow for the introduction of a spindle carrying a wound-up web of packaging material into the magazine unit, at least one pair of housing seats configured to rotatably support the spindle carrying the wound-up web of packaging material, the respective housing seats being arranged side-by-side and distanced from the inlet opening, and a pair of guide rails, the guide rails being arranged side-by-side and each one extending from the inlet opening to one respective housing seat and being configured to guide the spindle from the inlet opening to the pair of housing seats.

The present invention provides an adaptive control system to control a plant using direct output feedback in which a function of the full plant state, as opposed to estimates thereof, is used for feedback control of the plant. The adaptive control system of this invention is therefore highly useful in the control of plants, particularly plants for controlling the physical properties of rolls of web material and more particularly a calendering apparatus. Accordingly, in a particularly preferred embodiment the adaptive control system of this invention controls loading of a calender apparatus, such as a pair of opposed rolls forming a calendering stack, based upon the physical properties of a previously processed web.

A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.

Provided is a printing apparatus including: a holder unit provided with a holding member, a contact portion, and a shaft member, and an apparatus body provided with a support portion, and a fixing portion, wherein the shaft member is configured to be detachably attached to the support portion, the holder unit is configured to be rotatable between a first position and a second position with reference to the shaft member in a state where the shaft member is supported on the support portion, the first position is a position where the shaft member is attached to the support portion, and the second position is a position where the apparatus body fixes the holder unit by the fixing portion, the second position being a position where the contact portion is separated from the installation surface.

A system for automatic handling and sorting of narrow-slit rolls. Wherein the system is also capable of preventing toppling of the narrow-slit rolls.

A method of forming a gum roll is provided. The method includes providing a strip stock having a first end, a first surface, and a second surface opposite to the first surface. The first end of the strip stock is coupled to a core fixture so the first surface interfaces with the core fixture. The strip stock is rotated to wind the strip stock onto the core fixture such that the first surface interfaces with the second surface to form the gum roll. The method further includes cutting the strip stock to form the second end when the gum roll is wound to an outer roll diameter, the outer roll diameter being greater than a diameter of the core fixture.
