Sending Mail in loop w attachmt -> only 1.mail has the attachment

Hello,
i have a Loop where an email is sent to several adresses one by one.
works fine, but if i attach a file it works only for the first adress
correctly. THe other get the mailtext, but no attachment (coorct name,
but 0 Bytes)
Any Idea why?
TIA

Code of the controller:
def gruppenmail_schreiben
puts “------------------”
attach = params[:attachment]
params[:auftragnr].each do |t|
if t != ‘0’
neuemail = Writtenmail.new
neuemail.attachment = attach
neuemail.betreff = params[:betreff]
neuemail.body = params[:body]
neuemail.candidate_id = t
neuemail.absender = current_fakusers.email
neuemail.email = mailsuchen(t)
neuemail.save
mailsenden(neuemail)
end

end
redirect_to :controller => 'anzeige', :action => 'suchmaske'

end #Ende gruppenmail_schreiben

def mailsenden(mail)
Notifier.deliver_multipart_alternative_rich(
#t,#
mail.email,
mail.betreff,
mail.body,
mail.candidate_id,
mail.attachment,
mail.absender
)
#end
end #Ende mailsenden

models/notifier Code:
def multipart_alternative_rich(email, betreff, inhalt, nr, anhang,
absender, sent_at = Time.now)
require ‘mime/types’

@subject  =   betreff
@recipients = email
@from = absender
@sent_on =    sent_at
@body  =  {:inhalt => inhalt}
@content_type = 'text/html'

unless anhang.blank?
  datentyp = typerkennung(anhang.original_filename)
  puts datentyp
  attachment  :content_type =>  "'" + datentyp + "'",
              :body => anhang.read,
              :filename =>  anhang.original_filename
end

end

def typerkennung(dateiname)
dateityp = MIME::Types.type_for(dateiname)
return dateityp[0]
end

If the attachment is an IO like object (which seems like it is, from the
log), then you’ll probably need to rewind it after it has been read.
