Rewinder for the production of paper logs

Rewinder for the production of paper logs adapted to guide and transversely pre-cut a paper web along a predetermined path, adapted to wind a predetermined amount of the paper web on a core in a winding station, and including a threading mechanism for threading the web along said path. The threading mechanism includes a dragging unit provided to engage the web to drag it along the path with a predetermined feed direction and at least one dragging member to engage a respective flap of the web preceding the production of the logs. The dragging unit is located downstream of the winding station and is adapted to release the flap of the web from the dragging member, the release means being arranged downstream of the dragging so as to intercept the flap of the web and disengage it from the dragging while the web is fed.

SHEET FEEDING APPARATUS AND PRINTING APPARATUS
20210237998 · 2021-08-05 ·

There is provided a sheet feeding apparatus. A supporting unit rotatably supports a roll sheet formed by winding a continuous sheet into a roll shape. A first conveying path forming member is placed in a position spaced apart from the roll sheet supported by the supporting unit, and forms a first conveying path of the sheet. A displacing unit includes a guide portion capable of being displaced between a guide position and a retracting position set farther from a start position than the guide position. The guide portion is displaced from the retracting position to the guide position when a leading edge of the sheet separated from the roll sheet supported by the supporting unit is positioned between the guide portion in the retracting position and the start position.

AUTOMATED DEVICE AND PROCEDURE TO TRANSFER AND THREAD A BEARING BAND
20210179377 · 2021-06-17 ·

The invention relates to an automated device to transfer and thread a bearing band (3) on a fixed reel (2) from a removable reel (1), said reels (1,2) being joined and integral to corresponding shafts (4,5), wherein said device comprises a folding arm (6) adapted to perform a translational movement, which in turn comprises a hook (7) and a carriage (8) configured to move the arm (6) horizontally between both reels (1,2), and wherein the device further comprises a tensioning roller (10) adapted to move vertically through an intermediate column (11), such that it allows the first bearing band (3) to be transferred between reels (1,2) automatically in order to finally wind a second bearing band (12) with the first bearing band (3) onto the removable reel (1) automatically and simultaneously.

Disclosed is a cutting apparatus for a roll zebra. The cutting apparatus includes: a main body portion; a mounting portion provided at one side of the main body portion to wind or unwind a fabric; a cutting portion provided at one side of the main body portion to cut the fabric with a required length; and a discharge portion provided at one side of the main body portion to convey the fabric cut by the cutting portion to the outside. The cutting portion includes a longitudinal cutting portion cutting the fabric in a longitudinal direction, and a transverse cutting portion cutting the fabric in a transverse direction.

Dispenser cartridge and wiper with cord

A dispenser housing for dispensing a multi-layer tape transfer tape used in a paper web turn-up operation, the transfer tape being the combination of a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive and an affixed cord or cordlike feature, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer, the transfer tape being wound onto a single spool with the release liner facing inward and the mounting side adhesive facing outward, such that buckling is precluded when the transfer tape is unwound from the spool.

CORE WITH STRIP OR STRIPS OF VARYING DENSITY
20210139268 · 2021-05-13 · ·

A core for winding sheet material is proved. The core comprises a cylindrical tube having a longitudinally oriented slot formed therein, and a strip of soft material located in the slot. Because of the geometry of the slot and the strip, the strip may be softer in the central region but firmer where the core transitions from the relatively soft strip to the relatively hard tube. The leading edge of the sheet material imbeds itself into the soft central region of the strip as additional layers are wound around the core.
