A thermoforming packaging machine that includes a film holder for receiving a lower film supply roll and one behind the other in a sequential arrangement along a production direction a pretreatment station for pretreating the lower film web, a forming station for forming troughs in the lower film web by thermoforming, an insertion line for filling the troughs with products and a sealing station for sealing the troughs with a top film. A transport device is configured to transport the lower film web along the production direction through the pretreatment station, further to the forming station, further to the insertion line and finally to the sealing station. A deflection unit arranged at least partially below the pretreatment station is configured to deflect the lower film web before reaching the pretreatment station. The pretreatment station may include a punching or slitting unit to punch or slit the lower film web.

The invention concerns a splicing facility for splicing material webs. The splicing facility comprises a first dispensing device for dispensing a finite first material web from a first material web roll, a second dispensing device for dispensing a finite second material web from a second material web roll, a third dispensing device for dispensing a third material web, a first splicing device for splicing together the finite first material web and the finite second material web to an endless material web and a second splicing device for splicing together the third material web and the finite first material web or the finite second material web to the endless material web. The first splicing device and the second splicing device are arranged at different heights.

Method for predicting the presence of product defects during an intermediate processing step of a thin product wound in a roll, which provides forreceiving a roll of thin product that has been assigned a unique identification code stored in a database system, this latter containing process and/or product parameters detected in the production steps of said thin product wound in said roll upstream of said intermediate processing step, associated with said unique identification code, accessing said database system, entering one or more of the process and/or product parameters associated with the unique identification code of said roll contained in said database system in a predictive model, which uses a correlation, created by means of machine learning logics, from historicized values related to the process and/or product parameters output from said intermediate processing step and historicized values related to process and/or product parameters of the same rolls detected in the production steps of said rolls upstream of said intermediate processing step, in order to predict product parameters output from said intermediate processing step, comparing said aforesaid product parameters with respective predefined limit values, generating predictive diagnosis information of thin product defects based on the result of said comparison.

Process for the production of paper rolls, including a step of producing logs (L) of paper material by winding a predetermined amount of paper web (W) about a respective longitudinal axis, a step of transverse cutting of the logs (L) to obtain rolls (RO) of predetermined length, and an intermediate step of transporting the logs (L) from a rewinder (R) that produces the logs (L) toward a cutting-off machine (CM) that cuts them transversely. The intermediate transporting step involves the handling of the logs (L) along a path comprising a lateral deviation, so that, as they advance, the logs (L) are subjected to the lateral deviation.

The invention relates to a product marking in connection with a narrow roll. The narrow rolls are provided with a product marking in a first information adding step, the product marking comprising at least general information. In a second information adding step, the product marking in at least some of the narrow rolls is provided with customer information. After the second information adding step all the narrow rolls have a product marking comprising the customer information.

A machine for producing disposable products anticipates when a current run of a product size is coming to an end, and therefore begins loading of material rolls intended for the next product size or code that will be run. An integrated production facility layout automatically orders and stocks raw material based on production plans, and commands a production machine to produce specific products of differing configurations, and automatically loads appropriately sized raw materials into the process.

The invention concerns a splicing facility for splicing material webs. The splicing facility comprises a first dispensing device for dispensing a finite first material web from a first material web roll, a second dispensing device for dispensing a finite second material web from a second material web roll, a third dispensing device for dispensing a third material web, a first splicing device for splicing together the finite first material web and the finite second material web to an endless material web and a second splicing device for splicing together the third material web and the finite first material web or the finite second material web to the endless material web. The first splicing device and the second splicing device are arranged at different heights.

A method for unwinding includes loading a first reel of web material into a first unwind position where the web is unwound. A splicing unit is then moved in the machine direction toward the first unwind position until there is sufficient space to allow a further reel to be loaded into a second unwind position where the web from the second reel is unwound once loaded. Then, the web from the first reel is spliced to the second reel, and the web of the first reel is thereafter cut. The process continues in the opposite direction after removing the first reel from the first unwind position. The web of the second reel is unwound in the second position, the splicing unit is moved toward the second unwind position until there is sufficient space to allow a further reel to be loaded into the first unwind position.

Various embodiments of the present disclosure provide a coil-wrapping system (30) that simultaneously employs separate multiple film rolls (FR1, FR2) to simultaneously wrap separate films around a single coil while the coil is rotated about its longitudinal axis.

A base paper roll supply device includes: a first stand rotatably supporting a rear-liner base paper roll and a rear-liner replacement base paper roll; a second stand rotatably supporting a core base paper roll and a core replacement base paper roll; and a third stand rotatably supporting a front-liner base paper roll and a front-liner replacement base paper roll. The first stand, the second stand, and the third stand are arranged in order along a supply direction in which the rear liner, the core, and the front liner are supplied. At the first stand, the rear-liner replacement base paper roll is arranged at an upstream side in the supply direction with respect to the rear-liner base paper roll, and at the third stand, the front-liner replacement base paper roll is arranged at a downstream side in the supply direction with respect to the front-liner base paper roll.
