Introduction
The MATRIX CUBE has been developed by BTSR International S.p.A. to optimize the elastic yarn
application on automatic diapers production lines.
Since, for space reason it is impossible to install feeding devices (such as BTSR ULTRAFEEDER devices)
on the exact application point of the elastic yarns along the production line, an innovative solution based
upon two independent (yet interactive) tension control/adjustment systems has been developed:
•A first yarn tension control system at the application point, consisting of TS55 sensors (BTSR Patent).
•A second yarn feeding tension control/adjustment system consisting of one or more creels located at a
certain distance from the actual elastic yarn application point and based upon DIAPER FEEDER motor-
driven devices (BTSR Patent).
The two adjustment systems are controlled and coordinated by a CPU consisting of a SM-DIN/DUOLOOP
Board capable of communicating both with the TS55 sensors and with the DIAPER FEEDER devices via
RS485 serial lines.
The control/adjustment parameters of TS55 sensors and of DIAPER FEEDER devices can be programmed
through a SMART MATRIX CUBE terminal; this too can communicate with the SM-DIN/DUOLOOP Board via
RS485 serial line.
The SM-DIN/DUOLOOP Board may also be integrated (as an alternative solution) with the
production line management system, via industrial field bus (PROFIBUS). In this case, the
programming of TS55 and DIAPER FEEDER control parameters can be directly carried out by the
line control system.
Application Principle Layout

Introduction
MATRIX CUBE - ii -
The control/adjustment parameters (minimum/maximum tension, control activation delay, etc. on TS55
sensors, feeding tension, exit tension with machine stationary, etc., on DIAPER FEEDER devices) must be
programmed taking into account the possible variables (yarn elasticity, distance between TS55 sensors and
DIAPER FEEDER devices, friction generated by the various yarn sliding wheels, etc.), in such a way as to
find the most suitable values for each specific application.
Creel Structure
Considering the high operating speed of diapers production lines, notwithstanding the use of large capacity
yarn spools, an additional feature has been implemented to allow the junction of multiple spools on each
position (up to 4 spools), i.e. by connecting the tail of a spool with the head of the next spool, thus obtaining
a long operation capacity, without having to stop the machine to replace the empty spools.
The passing from a run out spool to the next spool is detected by yarn running sensors which inform the
operator about the occurred spool change through a message displayed both on SMART MATRIX CUBE
terminal and on the display of DIAPER FEEDER device that controls the involved position. This allows the
operator to replace the run-out spool, while the machine continues to operate with the new spool.
The MATRIX CUBE system may control up to 10 positions (10 elastic yarns).
The creels consist of stackable modules.
Each module controls an individual position and it comprises:
- a DIAPER FEEDER device
- a feeding spool unit (up to 4) (A)
- a “spool change” sensor (B)
Typically, the creels can be composed of 3 or 4 stacked modules.
Examples: 2 creels, each one with 3 modules, to feed 6 elastic yarns
only 1 creel with 4 modules, to feed 4 elastic yarns

Introduction

In particular cases, up to 6 modules can be stacked, adopting particular precautions to ensure creel stability
and operator safety during cleaning, spool replacement, maintenance operations, etc .

Manual Objectives
This manual has been written to provide the users of MATRIX CUBE system with the essential information
required to:
•Correctly install and connect the various system components (creel items, SMART MATRIX CUBE
terminal, SM-DIN/DUOLOOP control Board, DIAPER FEEDER devices, TS55 sensors, etc.)
•Configure the system according to the application needs and setup the various operation
parameters.
•Detect and interpret the error signaling and system efficiency data
•Use the diagnostics maintenance and utility functions offered by the system (system component
test, firmware upgrading, etc.).
How to Use this Manual
The manual is subdivided into 5 sections plus an appendix:
Section 1 – includes the connection diagrams and the electrical interface of the various system
components as well as the instructions for a correct assembly and loading of creels.
Section 2 – provides the operating instructions for a correct use of the SMART MATRIX CUBE terminal
as well as the parameter configuration/programming instructions
Section 3 – lists the possible error messages.
Section 4 – provides detailed information about the DIAPER FEEDER device.
Section 5 – provides the information needed for a correct preventive maintenance of the system.
Appendix A – provides an example of preliminary control procedure (Sign OFF) to be carried out at system
reception time.

Prescription for a Safe Use of the System
The parts of MATRIX CUBE system which may cause an exposure to the hazards listed on Harmonized
Standard EN ISO 14121-1:2007 Machinery Safety – Principle of Risk Assessment are the following:
- The electrical box on board of the creel, due to the presence of harmful voltages (380/480 VAC three-
phase)
- The DIAPER FEEDER devices due to the rotation of elastic yarn feeding motor
- The creel stability according to configuration (creel stacking possibility, frame mounted on wheel, etc.)
The protective measures to be adopted by the users are then the following:
The access to the inside of electrical box shall be allowed exclusively to skilled and
authorized maintenance staff.
During the system operation, the Plexiglas sliding protections of DIAPER FEEDER devices,
must be kept closed.
After any electrical maintenance work, make sure that the electrical box and the creel frame
are correctly connected to the protection earth system (PE clamp and stranded wires to
connect the various creel elements).
Whenever a creel cleaning or maintenance operation is to be carried out at a height
exceeding 2 meters, use exclusively a footboard, a self-stable ladder or a suitable lifting
device.
Never lean a ladder to the creel and never try to use the creel frame to reach the top side of
the creel itself. →Falling risk due to the movable creel, that leans on wheels
Prior to open the electrical box, always turn off the main switch or disconnect the power
cord
In case of creels composed of 5 or 6 stacked modules, the wheels must be replaced by
fixed supports anchored to ground or (as an alternative) 8 angle brackets must be fastened
to the 4 edges of the bedframe and to the ground (see example on picture A below).
Moreover, make sure that all the creel modules are tightly interconnected by means of the
stranded wires shown on the picture of Paragraph 1.3 “System power supply”.
The stranded wires must be applied at least on 2 opposed creel side, as shown on picture
B below
