Okukendeeza ku mpisa za anisotropic ez’embaawo ez’obutonde n’okukakasa eby’obugagga ebifaanagana n’enkula ennywevu, okutwalira awamu plywood enywerera ku misingi ebiri emikulu egy’enzimba: symmetry ne perpendicularity of adjacent veneer fibers. Enkola ya symmetry yeetaaga nti veneers ku buli ludda lw’ennyonyi ya plywood eya wakati eya symmetry zibeere symmetrical, awatali kulowooza ku mpisa z’enku, obuwanvu bwa veneer, omuwendo gwa plies, fiber orientation, obunnyogovu, n’ensonga endala. Mu lupapula lumu olwa plywood, ebiwujjo eby’ekika kimu n’obuwanvu bisobola okukozesebwa, era n’ebisenge eby’ekika n’obuwanvu obw’enjawulo bisobola okukozesebwa. Naye layers zonna ebbiri eza simmetiriyo eza veneer ku buli ludda lw’ennyonyi ey’omu makkati eya symmetry zirina okuba ez’ekika n’obuwanvu bwe bumu. Ebipande bya ffeesi n’eby’emabega bikkirizibwa okuba eby’ebika eby’enjawulo.
Plywood okusobola okutuukana n’emisingi gino gyombi emikulu, erina okuba n’omuwendo gwa plies ogw’enjawulo. N’olwekyo, plywood etera okukolebwa n’ennamba ezitali zimu eza plies, gamba nga ssatu, ttaano oba musanvu. Amannya ga layeri za plywood ge gano: ekibikka eky’okungulu kiyitibwa faceboard, eky’omunda kiyitibwa coreboard; faceboard y’omu maaso eyitibwa topboard, ate faceboard y’emabega eyitibwa backboard. Coreboard erimu fibers ezikwatagana ne faceboard eyitibwa long core board oba middle board. Nga okuŋŋaanya cavity board blank, waggulu ne backboard birina okutunula ebweru....
