A method for providing rolls of material for use in sheet form, particularly aluminum for food uses, comprising a step of rewinding the material for use in sheet form in order to form a roll; the rewinding step is provided by winding the material for use in sheet form directly on a rewinding shaft, with the material for use in sheet form in contact with a cylindrical outer lateral surface of the rewinding shaft, which is actuated with a rotary motion about its longitudinal axis, so as to obtain a coreless roll.

The present invention embraces a method and apparatus for improving ribbon replacement for thermal printers. The present invention also applies to replacement of other media in associated printers. The improvement is achieved based a ribbon adapter or media adapter that is designed for two conditions: 1) catch condition for printing, and 2) release condition for replacing the media in the printer. By a single click or press of a button, a user can switch between the two conditions. The printing operation occurs during the catch condition. The catch condition ensures that there is no or little relative movement between media core and media adapter. The media adapter can also support different diameter media cores. The release condition is implemented when the user replaces media. The release condition can provide a relatively easy replacement of a media without a significant force or pressure.

Machines are disclosed for dispensing a rolled fabric over spaced support beams of a roof and for holding the fabric firmly in place over such beams to protect workers from falling through the gaps between the beams. The machines may include one, some, or all of several different components and features to enhance the system's overall operation and effectiveness. One aspect relates to a hub brake used to help prevent unwinding of the fabric roll in the event of a fall. Another aspect relates to a magnetic brake to help keep the machine from sliding across the support beams in the event of a fall. Another aspect relates to a guide assembly that engages a support beam with a one-directional bearing to also help keep the machine from sliding in the event of a fall.

A collapsible rewind spindle includes a main spindle body, and a filler spindle body removably coupled to the main spindle body and movable between an expanded position a collapsed position relative to the main spindle body. A release assembly is provided for allowing movement of the filler spindle body from the expanded position to the collapsed position. A release assembly is provided for allowing movement of the filler spindle body from the expanded position to the collapsed position, wherein the release assembly is configured to effect a controlled movement of the filler spindle body from the expanded position to the collapsed position.

The present invention is an apparatus, system and method for a new and improved coiling head utilized in wrapping elongated materials, which may have a zero and or near zero gap between leaves thereby reducing and or elimination indentations in the coiled elongated materials.
