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 disclosure provides an apparatus for manufacturing a superfine fiber roll wiper for a cleanroom, wherein a thermal cutting unit including thermal cutting blocks and thermal cutters is applied to a thermal cutting part, such that a process of manufacturing a roll wiper and a process of thermally bonding both ends of the manufactured roll wiper may be performed by the single apparatus, as a result of which, with the use of the single apparatus, it is possible to considerably improve workability, implement the mass-production, and reduce manufacturing costs. Further, the thermal cutting unit further including interval adjustment blocks in addition to the thermal cutting blocks and the thermal cutters is applied, such that a width of a roll wiper to be manufactured may be selectively and conveniently adjusted when a change in width of the roll wiper is required.

An improved winding apparatus and system for winding strips of web materials.

A product packaging tape winding device includes a moving bracket, a rotating shaft which is rotatably mounted on the moving bracket, and two groups of reels. The rotating shaft has two shaft parts extending from both sides of the moving bracket. The two groups of reels are installed on respective ones of the two shaft parts of the rotating shaft to rotate with the rotating shaft. The device is adapted such that when one group of reels has been fully wound with the product packaging tape, the moving bracket is moved to move the one group of reels from a working position to a standby position and move the other group of reels from the standby position to the working position, so as to continue winding the product packaging tape with the other group of reels.

The machine (1) comprises: an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N; S); at least one winding station (15) comprising a winding device (25) and further comprising: guide members for guiding the strip (S) of web material, configured to form at least a loop of web material between a guide roller (43) and a log (B); and a cutting device (61) for transversally cutting the strip (S) of web material in an intermediate position between the log (B) and the guide roller (43), thus generating a tail edge, remaining on the log (B) being formed, and a leading edge, remaining fastened to the guide roller (43).

An improved winding apparatus and system for winding strips of web materials.

A machine (1) includes an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N), an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (Na, Nb), and at least one winding station (15). The winding station in turn includes a winding device (41, 51), to which a longitudinal strip (S) of web material is fed. In the winding station, a respective spool (B) of web material is formed. The winding station (15) further includes: a cutting device (81, 83) for the longitudinal strip (S), to cut the longitudinal strip (S) transversely, thus forming a tail edge, which remains on the spool (B) under formation, and a leading edge; and a holding device (85) for holding the leading edge of the longitudinal strip (S), to transfer the leading edge onto a tubular winding core (T) of a new spool to be wound.

The invention describes a roll-removal device by means of which a plurality of rolls which have been wound to completion are transported away from a winding shaft having a displacement device for displacing the rolls relative to the winding shaft, in order to withdraw the rolls from the winding shaft, having a receiving device for receiving the rolls, and having a transfer device for transferring the rolls from the displacement device to the receiving device, wherein the rolls can be rolled freely at least in certain regions, the rolls rolling about their rolling axes. By means of this device for changing the position of the rolls axes, the roll axes of two adjacent rolls can be moved to an angle of less than 180 degrees in relation to one another.

To provide (i) a method for producing an assembly capable of protecting a film from external force during, for example, transport and (ii) such an assembly, a method for producing an assembly includes a step of inserting a pillar-shaped core member through a plurality of separator rolls and a buffer member(s) made of a flexibility material and provided between separator rolls such that the separator rolls and the buffer member(s) are arranged alternately.

A wagon (90b) includes a plurality of horizontal support bars (91f). A separator roll (12b) is stocked while the horizontal support bar is inserted into a core of the separator roll (12b) around which core a separator is rolled. This can prevent deformation and roll misalignment of the stocked separator roll.
