A process is provided for heat sealing substrate layers. The process comprising: conveying an upper die having a heating conductor and a lower die having a heating conductor to a sealing region, where a substrate is applied to one or more items; activating a power supply system; monitoring, via the power supply system, a temperature of the heating conductor of the upper die when in the sealing region; monitoring, via the power supply system, a temperature of the heating conductor of the lower die when in the sealing region, wherein the monitoring of the temperature of the heating conductor of the upper die is performed independently of the monitoring of the temperature of the heating conductor of the lower die; supplying power to the upper die based on the temperature of the heating conductor of the upper die; supplying power to the lower die based on the temperature of the heating conductor of the lower die, wherein the power is supplied to the lower die independently of the power being supplied to the upper die.

A method for forming a package including a stack of absorbent tissue paper material and a packaging, the tissue paper material in the stack forming panels having a length, and a width perpendicular to the length, the panels being piled on top of each other to form a height extending between a first end surface and a second end surface of the stack, and the packaging encircling the stack so as to maintain the stack in a compressed condition in the package, with a selected packing density D0 of the stack, and a selected packing height H0; the method including: forming the stack of absorbent tissue paper material; compressing each portion of the stack in a direction along the height to assume a temporary height H1 being c1×H0, where c1 is between 0.30 and 0.95; and applying the packaging to the stack.

A process is provided for heat sealing substrate layers. The process comprising: conveying an upper die having a heating conductor and a lower die having a heating conductor to a sealing region, where a substrate is applied to one or more items; activating a power supply system; monitoring, via the power supply system, a temperature of the heating conductor of the upper die when in the sealing region; monitoring, via the power supply system, a temperature of the heating conductor of the lower die when in the sealing region, wherein the monitoring of the temperature of the heating conductor of the upper die is performed independently of the monitoring of the temperature of the heating conductor of the lower die; supplying power to the upper die based on the temperature of the heating conductor of the upper die; supplying power to the lower die based on the temperature of the heating conductor of the lower die, wherein the power is supplied to the lower die independently of the power being supplied to the upper die.

Converting line for paper rolls, including at least one converting apparatus adapted to convert paper plies, wound in parent reels, into rolls, a packing machine that in turn includes—a carrier conveyor, on which the rolls coming from the converting apparatus are arranged, —at least one side area at the side of the carrier conveyor, where the rolls are packed, —at least one robot adapted to take the rolls from the at least one conveyor belt and to put them in the at least one side area.

A method for producing enveloped electroscopic filter material can include feeding, from a main spool, at least one sheet of electroscopic filter material in a first direction, feeding, from a pair of spools, sheets of cover material in the first direction such that each spool feeds a sheet of cover material along a different side of the sheet electroscopic filter material, sealing, via a pair of heat-sealing roller nips, the at least one sheet of electroscopic filter material and the sheets of cover material periodically together to form sealed portions, and cutting, via a cutting mechanism, each sealed portion to produce envelopes of electroscopic filter material. The at least one sheet of electroscopic filter material can extend to the outermost edges of each envelope such that each envelope comprises substantially the same dimensions as the at least one sheet of electroscopic filter material.

Apparatus for manufacturing mailpieces, comprising a supply module for supplying cold seal paper to form an envelope body, a feeding module for collating documents to form the content to be inserted in the mailpiece, and a pair of finishing rollers for folding the envelope body around the content and sealing the mailpiece in a single finishing step.

A vibrating device (14) ensures the ordered rearrangement of folding boxes (3) in a receptacle (2) for an evacuation conveyor (8), provided with driving elements (12) whose vertices define a horizontal transport plane (S2). The device comprises: a movable support (15) able to support a receptacle (2) loaded with folding boxes (3), the support (15) having a contact surface (S1) designed to be in contact with the receptacle (2), and at least one controllable actuator (16a, 16b, 16c, 16d) comprising a displaceable end connected to the support (15) and able to displace the support (15) between: a retracted position in which the contact surface (S1) is positioned beneath the horizontal transport plane (S2), allowing a contact between the receptacle (2) and the driving elements (12), and a deployed position in which the contact surface (S1) is positioned above the horizontal transport plane (S2), preventing the contact between the receptacle (2) and the driving elements (12),
the actuator (16a, 16b, 16c, 16d) being likewise designed to cause the support (15) to vibrate about the deployed position in order to reorder the disposition of the folding boxes (3) contained in the receptacle (2).

To provide a method and an apparatus for manufacturing pillow packages provided with a fixing tape with high efficiency while preventing damage to the pillow packages. The method for manufacturing pillow packages includes placing a pillow package 1a among a plurality of pillow packages conveyed by a conveying section 21 on an inclined placement section of the conveying section 21 to incline the pillow package 1a in a predetermined direction to thereby expand the gap between a pillow package 1b placed next to the pillow package 1a on the conveying section 21 and the pillow package 1a and bringing a cutting blade 25 into contact with a string of double-sided tape 16 bonded between the pillow package 1a and the pillow package 1b to cut the double-sided tape 16.

A heating block assembly including one or more configurable insulator segments and a heater block having a first surface configured to removably receive the one or more configurable insulator segments, in which each of the one or more configurable insulator segments covers only a portion of the first surface. A method for sealing at least one portion of a package using such a heating block assembly is also disclosed.
