The focus for this study is the illumination of the function of loom weights and their purpose within the warp-weighted loom. This study deals with Iron Age loom weights excavated at Birka, within the area known as the Garrison. This category of objects was originally classified as being fragments of bellow shields, an interpretation seemingly more corresponding with the site’s traditional interpretation. In order to give a fuller depiction of the textile production as a whole, spindle whorls found within the same defined area have also been included in this study. The main goal for the analyses of these two groups of fragmented finds has been to establish and re-create the functioning variables of these objects, that is, foremost their original shape and weight. Furthermore the objective has been to enhance the understanding of the functional parameters of the textile production in this area. This is partly achieved with the aid of comparing data regarding textile implements found in other areas of Birka. The results can confirm that the area held a capacity to manufacture a variety of different textiles, including very fine threads and weaves.

Denna kandidatuppsats behandlar sländtrissor och vävtyngder från vikingatida lokaler samt yngre järnålderslokaler som angränsar till den vikingatida handelsplatsen Birka. Syftet är att studera sländtrissor och vävtyngder från vikingatida fyndlokaler i Birkas omland; vilket åsyftar geografiska områden i Södermanlands län (Södermanland), Stockholms län och Uppsala län (Uppland). Sländtrissor påverkar de textila råmaterialen och de spunna trådarna, vidare påverkar vävtyngderna varpen och de vävda tygerna. Vilka trådar och vilka tyger som har producerats inom vikingatida lokaler i angränsning till Birka diskuteras utifrån sländtrissornas och vävtyngdernas vikt, form och storlek (trots att fragmentariska artifakter förekommer). Studien omfattar spår av textilproduktion inom vikingatida lokaler i Birkas omland, samt en undersökning gällande om det har förekommit inhemska importer av textilier från fastlandet till Birka under vikingatiden. Resultatet påvisar om att gårdsbaserad textilproduktion har förekommit i Birkas omland och ett fåtalet gårdar i omlandet tolkas ha haft möjlighet att exportera textilier till Birka. / This bachelor thesis is regarding spindle whorls and loom weights from late Iron Age-sites and Viking Age-sites in adjoining relation to the Viking Age town Birka. The basis of this thesis concerns in which amount spindle whorls and loom weights occur at Viking Age-sites in Birka's hinterland; it refers to geographical areas in Södermanland County and Uppland County. Spindle whorls influences the textile raw materials and the spun threads, furthermore loom weights influences the warp and the woven cloths. Which threads and which cloth that were produced at the Viking Age-sites in adjoining relation to Birka will be discussed by regarding the weight, form and size of the spindle whorls and loom weights (though fragmental artifacts occur). The thesis will concern trails of textile production from Birka's hinterland and furthermore an investigation about domestic imports of textiles from the mainland to Birka could have oocurred during the Viking Age. The Results indicates that farmbased textileproduction has occured in Birka's hinterland and furthermore numerous of the farms in the hinterland can be discussed as farms with the possibility to export textiles to Birka.
