### The Design and Construction of SRMF
#### 3.3.1. The Minting Process by Roller and the SRMF Architectural Layout  
The different activities related to the minting process by roller can be grouped into the following categories:  
* Intrinsic: All activities related to the process of creating alloys and casting the alloy strips from which coins were manufactured. * Extrinsic: Tasks associated with the mechanical, thermic and chemical treatments applied to the alloy strips used in the manufacturing of currency. * Auxiliary: Includes activities connected to machinery maintenance, as well as engraving, forging and lathing processes. * Administrative: This category can be divided into two subgroups. The first includes all activities related to the guard and custody of raw materials (metal ingots), alloy strips, coins and metal alloy scraps generated by the blank cutting process, while the second encompasses all activities linked to the registration and verification of the weight and quality (also called Law) of the metals employed to create the alloys, as well as the alloy strips, coins and metal alloy scraps resulting from the blank cutting process. A list of the roles necessary for the operation of the SRMF, along with a brief description of their corresponding duties, is displayed in Table 2, below. The sequence of activities that make up a cycle in the production of currency at the SRMF, from the beginning--when the raw material, metal, enters the production chain--until the end of the manufacturing process--when the final product, in the form of coins, is obtained--is shown in the flow charts of Figures 2 and 3. Both charts have been based on those shown in [2], on pages 60 and 61. \begin{table}

Table 2: Roles and responsibilities (prepared by the authors, based on [11]). \"Ingenio Grande\" and \"Ingenio Chico\". A water system located between the \"Ingenio Grande\" and \"Ingenio Chico\" buildings channelled water to power the waterwheels, located along the facade of the \"Ingenio Grande\". The activities that made up the currency-minting production chain were organized among the different buildings of the SRMF, as follows:  
Edificio del Patio Alto: This building was the SRMF management headquarters, and, until 1730, it was run by the Treasurer. This was where the input of raw material, (metal ingots) and the output of finished product (coins), took place, and where administrative and intrinsic activities were carried out. From the moment the metal ingots entered the production cycle, each stage of the process was carefully registered and controlled: the registration and verification of the grade and weight of metal used to cast the alloy strips, the alloy strips themselves and the coins obtained from them. From this building, the alloy strips were sent to the \"Ingenio Grande\" and came back in the form of coins and alloy scraps.
