摘要:
A packaging process line that compacts rolled products as they are packaged is disclosed. A firmness measuring device (10) is used to measure the firmness of the rolls (24) as the rolls, for instance, enter the process line. The roll firmness device is placed in communication with a controller (26), such as a microprocessor. The microprocessor is configured to receive information from the roll firmness device and control one or more elements within the process line that apply a compressive force to the rolls. In particular, the controller is configured to adjust any packaging equipment that applies a compressive force to the rolls so that a substantially uniform amount of force is applied to the rolls throughout the system. In this manner, the system is capable of automatically making adjustments based upon any variation in the product. Misfeeds, miscounts and the like are minimized for improving a packaging process line that compacts rolled products as they are packaged is disclosed.

摘要:
A novel apparatus and method for processing high bulk tissue webs are disclosed for depositing an aqueous suspension of papermaking fibers onto an endless forming fabric to form a web, drying the web to form a dried web having a bulk of 9.0 grams per cubic centimeters or greater, winding the dried web to form a plurality of large diameter parent rolls wound on a core, and transporting the parent rolls to an unwind stand having torque transmitting clamping means (160) for engaging opposite end surfaces of the parent rolls. A backing plate (168) is operably connected to and rotatable with an unwind shaft (162) connected to an electric drive. An inflatable bladder (164) is mounted on the backing plate. The clamping means engage a first parent roll (R) by inflating the bladder such that the opposite end surfaces of the roll are sandwiched between the side clamping mechanisms for partially unwinding the first parent roll using a variable speed drive operably associated with the clamping means.
摘要:
A method for processing high bulk tissue webs includes forming a wet web, drying the web, winding the dried web to form a plurality of parents rolls (R), unwinding the parent rolls by transmitting torque through the roll center and/or ends, moving the partially unwound roll to effect splicing with a subsequent parent roll, and rewinding the thus united web. In particular embodiments, the torque transmitting means (20) comprise side clamping mechanisms that engage only the end surfaces of the parent rolls. In other embodiments, an automated off-line method for splicing tissue webs from different parent rolls utilizes a finishing unit (23) that substantially continuously impacts each web during unwinding the splice the webs together.
