Help with some translations? (to portuguese but any help is appreciated)

[zukriuchen]

So, I'm doing some translations, and usually I get a translation for one or two words I don't know on google or something, but I've been having problems with these specific ones, because they're a little more technical I guess? All I know is that they're related to machinery and I really don't know how to translate them

So, if you don't speak portuguese, just gimme any other meanings you know for these words. Remember, it's related to a machine (they don't really give out many details for what exactly I'm translating so I don't even know what kind of machine)

"Sleeve magazine" (really no clue what this one is)
"Carton guides" (yes I know what carton is, but could it have a different meaning?)
"Jig"
"Infeed" (I sorta know what this one is but I'm not too sure on how to translate it, or if I should trust google's results with synonyms since they might not be in the same context)

Really, if you can just tell me some synonyms (as long as they fit in the same context), that'd really help, thanks in advance
