The invention relates to an assembly for positioning a heater in relation to a roll, wherein the roll (101) has a substantially cylindrical shape with a shall surface (103), rotatable around a shell axis (102), at a first distance (104) from the shell axis (102). The heater (105) comprises at least one heater section (106, 106', 106") intended for heating the shell surface (103), and is supported via a suspension attachment (107) by means of a supporting means (108) on a variable, second distanc...

A post processing cap applicator for applying a cap to a closure spout after erection, spout attachment, filling and sealing of a carton accommodates custom caps. Cartons are conveyed through the applicator in a first forward direction. A cap supply is configured to dispense caps and to position an edge of a cap in a path defined by movement of the closure spout through the applicator. The closure spout engages the edge of the cap. The applicator includes a rotating, torque-applying element and ...

Method and device for measuring a folding angle of a sheet (6,25,26) in a folding machine, whereby a number of distances are measured in a plane (28) that crosses the sheet (6,25,26) and the element (4,24,7), whereby a distance profile (19) of the measured distances is determined, and whereby the folding angle (A) of the sheet (6,25,26) is determined as a function of the angle (B,B1,B2) between the sheet (6,25,26) and the element (4,24,7).

A support for supporting a power tool (3) on a displacement carriage (2) and including an attachment element (7) for connecting the power tool (3) with the carriage (2), and a bolt insertable into an eyelet (8) of the power tool (9) for releasably connecting the attachment element (7) with the power tool (3) with the bolt (6) having axial and radial conduits (12, 13) communicating with an outer cylindrical surface of the bolt (6), so that predetermined position of the bolt (6) in the eyelet (8),...

A nail gun and depth control spacer assembly for ejecting nails into a substrate which contains two or more layers of roofing materials one of which is a compressible fibrous layer. The nails penetrate the substrate but are prevented by the depth control spacer from permanently compressing the compressible fibrous layer which springs back to is original thickness after completion of the nailing process. The depth control spacer, attached to the base of the nail gun, is of semi-oval configuration...

A sealing device includes a top part forming a bell and a bottom part forming a vat, receiving a container to be sealed with a film in the chamber defined by the top and bottom parts. The top part includes on a side supplying the film, a slot for the passage of the film running through a wall of the top part, and a device, preferably an inflatable pipe, for obstructing the slot and blocking the film. The wall of the top part also includes a device for inserting and/or extracting fluid, opening i...

In a machine for packaging stacks of multiply articles of paper into wrapping sheets, a first line conveys stacks of multiply articles of paper to a a wrapping station while a second feeds wrapping sheets to the wrapping station. Each sheet is kept vertically in a waiting position in the wrapping station until one stack is moved towards the sheet, so that the sheet gradually folds around the stack with overlapping parallel edges to be heat-welded. In the said second line there are first endless ...
